Noise Pollution

Noise Pollution

28/3/2011

What is noise? Have you heard the word "noise pollution"? Well, I don't know as well but I think I will enjoy learning it like you want to learn too. Noise, Latin word nauseas, meaning seasickness, is a dissonant sound; now you learned what a noise is, what is a noise pollution? Noise Pollution is an unpleasant sound, disturbing, and annoying, simply described as "environmental noise, " produced by machines, which afflicts one; basically, noise pollution is an unwanted sound created by human beings. Some of the expressions or noise pollutions we hear everyday are:

Transportations (traffics)

Dog barking

Toilet flushing noise

Scratching against the board

Effects of Noise Pollution:

As we all studied noise pollution, noise pollution is a disturbing sound; now we learn the effects. The main effects of noise pollution are human health, annoyance, speech and sleep interferences, and last of all decreased work performance. These lists given might sound weird to you, but noise pollution influences a lot of these categories.

Human Health: The noise pollution is one of the main causes of human health; it disturbs our behaviors and the health of one. Some of the solutions resulting from the noise pollution are indigestion, high blood pressure, lack of sleep, and heart disease. As a result, one will be mentally ill, and will be arduous to keep one’s life.

Annoyance: The annoyance in this case stands out for the volume of the sound. It can be expressed that lower levels of noise are irritating and also high volumes can be annoying. Science has proved that natural sounds are less irritating than intermittent sounds, one will most likely to react frustrated when one got disturbed by “a tap dripping water than falling rain.”

Speech and Sleep Interference: Speech and Sleep interference accounts for the limits and the condition of one reacting to the noise pollution. A person will frustrate when a noise of 50dB is produced since a noise that formidable to interpret can be a problem to one. On the other hand, when a high level noise disturbs one (such as my parents), they will react very furiously, telling that one should not be annoyed when sleeping. If this continues, one will feel tired or not energetic, so as said that, one should not afflict someone when he/she is sleeping.

Decreased work performance: Have you ever procrastinated before? Is it due to the disturbing noise produced from television? Have your parents ever say “Increased noise levels gives rise to a lack of concentration and accuracy at work.” They are trying to warn you that, your active brain, which simultaneously has to work both things (watching TV, and studying) at the same time, could lose concentration causing accidents.

Possibilities of helping/avoiding/eliminating Noise Pollution:

As you learned the objective of today “Noise Pollution,” and the effects, you can learn about the works to help, avoid, and eliminate noise pollution.

Now you are going to choose a nice abode to live in; you have chose your house and settled. Next to you, lives a rock band singing all day long, on the other side, there are elders fighting. Since you are at the edge of the block and on the first floor, you hear people passing by, cars driving, even constructions going on around the city. When you take a walk, you see barking dogs; also, the worst thing you can ever imagine is that you live next to the airport. Everyday living in this life won’t be easy, how about moving out.

It’s not all about moving in a nice place, it’s about choosing the suitable place for your personal needs (health). These ones above were the best story that one will never want to be involved in, if you want to avoid this matter, be thinking about the noise pollution.

The Loudness Lab

Loudness Lab

Kyle C.

I. GUIDING QUESTION/S (State the guiding question/s):

How does density of various solids affect the way the sound waves travel from the turning fork?

II.HYPOTHESIS:

Kyle’s Hypothesis: I believe that the responding variable (especially vibrations) of wood will likely last longer and be very loud due to the thickness.

Control=Force, Tuning fork, Frequency, Length, Temperature (Loudness change)
Manipulated=Materials, Temperature
Responding=Pitch, Loudness, How long the sound lasts (Properties of sound)

III. Exploration (PLAN & DO A TEST):

(Materials)

Tuning Fork
Metal
Plastic
Wood
Paper
Notebook
Pencil (To record)

(Procedure)

1. Find and gather the densities of following materials below.
2. Use a tuning fork; hit it against a manipulated variable.
3. After banging towards the object, place the small part or the edge of the tuning fork towards your ear.
4. Record the vibrations and the loudness of the manipulated variable.
5. Use this method to find the loudness of the other materials.

IV. RECORD & ANALYZE

A. Data Tables:

Tuning Fork: 512C
Weight: 27.3g

	Metal	Wood	Plastic	Paper
Density	7.85g/cm3	5kg/cm3	7.85g/ml3	0.78g/cm3
Loudness	Boisterous or could be expressed as very loud	(Ultra) So Loud and its vibration lasts long as if it was noisy (disturbing)	Bit loud, Bit soft, it is arduous to determine	Very Soft; can’t hear that much
Other Observations	Measured on the metal attached to the board. The sound of the metal had caused disturbances to the classmates next to me (vibrations last for a lot.)	Measured a wooden chair Could have similar frequency with metal	The plastic containing no materials didn’t vibrate that long due to the manufacture quality (plus, the loudness might vary on the value and the quality)	The paper lasted only about 1 sec, the vibration lasted very short. Maybe the heavier the manipulated variable, vibration last longer
Vibration (Time Lasting) 3 Trials	10 Sec 8 Sec 8 Sec	11 Sec 10 Sec 8 Sec	4 Sec 4 Sec 3 Sec	2 Sec 1 Sec 1 Sec

C. Analysis of Data:

Kyle’s Analysis:

The results above show that the metal (could be wood as well) will likely produce vibrations, which will last longer and the loudest volume.
I also figured out that it might be possible that heavier the manipulated variable, vibration last longer.


IV. Concept Acquisition (CONCLUSION):

My hypothesis “I believe that the responding variable (especially vibrations) of wood will likely last longer and be very loud due to the thickness,” was applicable in this lab but I assume that more manipulated variables will be required in-order for my hypothesis could be correct. Also, metal and wood will likely to have the equal amount of frequency perhaps due to the similar vibrations records. As you can see above, the results suggests that higher the density, vociferous it will be; what really concerns me is that the density of the plastic expressed as “cm,” might disturb the data table since neither Riena and I knew if we should leave it as it is or change it to make the units all same. Another problem is the weight of the tuning fork, as I thought, depending on the weight of the tuning forks, results will vary. So in conclusion, depending on the thickness of the responding variable, adjustments can be made, and last of all but not least, the weight of the tuning fork could vicissitude.

V. Concept Application (FURTHER INQUIRY):

As to write my further inquiry, I would like to account for the improvements and causes of this lab; though we didn’t have miscommunication or any major mistakes we (well mostly I) had troubles due to partner departure. On the other hand, the major causes of error were probably incorrect density records or confusion upon the weight of the tuning fork. When I was working on the lab, I had confusion that my hypothesis will be wrong since depending on the weight of the tuning fork, answers will alter. The improvements I can make if I have to re-dew this experiment will be choosing a different responding variable to try something new and not letting the partner I am with leave me since I have to do a lot of work then. As said, if my predictions were to be all correct, I can assume that this was actually an engaging lab, due to the fun of experimenting the tuning fork.

Listening to Sounds Lab

Listening to Sounds Lab

Kyle C.

7A

Purpose: to determine a way to amplify sound traveling to your ear.

Procedure:

1. Tie 2 strings to the handle of a metal spoon. Each string should be about 40 cm long.

2. Hold one end of each string in each hand. Bump the bowl of the spoon against a desk or other hard, solid object. Listen to the sound.

3. Now wrap the ends of the string around your fingers.

4. Put your index fingers up against your ears and bump the spoon against the object again.

Conclusion:

How does the first sound compare with the sound you heard with your fingers up against your ears?

The vibration became stronger; it also sounded deeper.

How did the sound travel to your ears when you had the string touching your ears?

The vibration traveled through the string.

Why do think it was easier to hear the sound when you put the strings by your ears?

It was easier to put the strings next to our ears since we were tightening the string to make it denser.

Purpose: To determine how changing amplitude and frequency can change how a sound is perceived.

Procedure:

Experiment no.1: Amplitude

1. Have 2 partners each hold one end of the thicker rubber band and pull until the rubber band is taut (not loose).

2. Pull the rubber band about 1 cm away from the middle. Let it go. How far does the band move? Describe the sound you hear in the table below.

3. Repeat step 2 four more times. Each time, pull the band back further. Describe how the sound changes each time in the chart below.

Experiment no. 2: Frequency

1. Have 2 partners each hold one end of the thicker rubber band and pull until the rubber band is taut (not loose).

2. Pull the rubber band about 2 cm away from the middle. Let it go. Observe the sound.

3. Repeat step 1-2 with the thin rubber band and describe the difference in the chart below.

4. Now, take the thicker rubber band again. Repeat 1-2.

5. Now pull the thicker rubber band a little bit tighter and repeat steps 1-2. Observe how the sound changes.

6. Pull the rubber band even tighter and repeat steps 1-2. Observe how the sound changes. Record your observations in the chart.

7. Last experiment: have two partners hold the thick rubber band just like in step 1. Repeat step 2 and observe the sound.

8. Now, have one of your partners move his or her hand so that the rubber band is a little bit shorter. Repeat step 2 and observe the change in sound.

9. Repeat step 8 2 more times, making the rubber band a little shorter each time. Record your observations of the change in sound.

Results:

Experiment no.1

Distance away from middle	Description of sound
1cm	Low pitch
2cm	Bit higher than before but still low
3cm	Average
4cm	High pitch
5cm	Very high

Experiment no.2

Thickness of Rubber Band	Description of Sound
Thick	Sound of base guitar
Thin	Sounds like a guitar which needs to be tuned (tuning problem)

Tightness of Rubber Band	Description of Sound
Loose	Can’t hear anything
Tight	Sound like deep
Tightest	Loud

Length of Rubber Band	Description of Sound
Longest	Average sound
Long	Loud and High
Shortest	Bit higher than before

Conclusion:

1. How did the sound change when you changed the amplitude (how far the rubber band was away from the middle point)?

My record suggested that when adjusting the amplitude of the rubber band, the pitch when increasing will become exquisite like it will form beautiful sounds.

2. What happened when you changed the thickness, length, and tightness of the rubber band?

When I altered the thickness, length, and tightness of the rubber band, the sound and volume of them increased (for some reason).

3. Sally is playing the guitar and notices that one of her strings is flat (pitch is too low.) What can she do to fix this?

Sally should tighten the string the guitar to make it better. (Increasing the pitch)

Design a Seismograph Lab

Design a Seismograph Lab

Discovery of reaction to the weight when the wave is added

Kyle C.

2/7/2011

Objective: Find the reaction of the wave (seismograph) when the weight attached

I. GUIDING QUESTION/S:
What will occur when different weights are added to the surface wave (Finding the work of seismographs)?

II.HYPOTHESIS:
Kyle: I believe that depending on which or how much the weight, the solution of the balance will vary.


III. Exploration (PLAN & DO A TEST):

Materials:

Previous Fail Trial Materials:

Red Pen
Blue Pen
Chicken Wire
Scissors
Board Game for the bottom
Tape
Wagon Wood Wheel
Paper
Weight
String

New Trial Materials:

Pen
Weight
Tape
Paper
Ruler
Science Discovery Book
Chicken Wire
Table (As an earthquake)

Procedure (New Seismograph Procedure):

(After Gathering the Materials above)

1. First attach/tape the tip of 2 rulers to the wall horizontally and parallel
2. By using the tap attach the chicken wire to the rulers.
3. Then connect the pen to the wire, which holds the weight. (The objective is to see, if adding weight will affect the result )
4. The pen should be stationary; the pen will be producing seismogram.
5. When the pen with weight is connected with the rulers, slowly prepare the papers and the table to produce earthquake (magnitude).
6. Let one person move the paper slowly when one or two shakes and create earthquake movements.
7. As a result, the seismogram will show the wave vibrations.


IV. RECORD & ANALYZE

Failed Attempt

Successful attempt

Data of Seismogram Analysis:

Kyle’s Analysis of the Seismogram:

The Graph shown above shows our final data of the new seismograph we made. As the seismograph reacted by the magnitude of the table, the wavelength and the frequency of the seismogram altered. The monitor up there shows how fast and how hard the magnitude reacted. In final consideration, the new seismograph we made was efficient, simple, and easy. I had discover that the seismogram will show difference results when depending on the weight; as more weights are included the shorter the wavelength will be and faster the vibration or the movement.

C. Analysis of Data:

Kyle’s Analysis: I had figured out that the result and the affect of the wave movements will alter depending on how many weights are added to the pen.


IV. Concept Acquisition (CONCLUSION):

Kyle’s Conclusion: There are several conclusions to write down; mistakes and trials were made throughout the tests, some were successful but majorities weren’t. As our class started the seismograph lab, my group partners had left without a sign. Though this wasn’t the major problem it could had caused a huge impact. But the problem of this lab was that many attempts were made, however not a single we expected came out. All of us had discovered that the pen should had been stationary, if not we had to adjust the box (it was arduous to adjust since the box was about to be ripped). As my group mates knew this matter, we needed support or a change, we lost control when we were trying to aim higher.


V. Concept Application (FURTHER INQUIRY):

Kyle’s Further Inquiry: It is really difficult to mention all the improvements we have to look for when we try this lab again; if we actually have a chance to work this out again, I would be concentrating more on the actual seismograph instead of improving it to make it better. On the other hand, I believe that our seismograph lab didn’t work out that well was due to the cooperation condition, I discovered that having a lot of group members in my group won’t going to work since then, we need to care if others are on the right track. As a result, the work won’t be successful, however I felt that our work was organized since all of our group members wanted to be tidy during the project. Other wise just being sure the pen is stationary, I am proud of the work. In conclusion, the seismograph is a useful method to detect the seismic waves but when it gets to making one, we have to see about that.
