Noise and hearing!!!

Noise Pollution

Noise pollution can be a very big problem and it can also have a great affect on people in the area. Noise pollution can come in many forms. Below i will give examples of how it comes and how it can effect people. 

What is Noise Pollution? 

 Noise pollution is a type of Pollution and it can be a energy pollution as well. There are all kinds of energy pollution like, Light and heat pollution. Noise pollution comes from, Barking dogs, cars/ motorcycles, trains, loud music etc. 

What are the effects of Noise Pollution? 

Noise pollution can Distract, Irritate, and also can hurt humans health, like deafness, cant sleep, heartburn high blood pressure etc. Noise pollution gets rid of other natural sounds and interferes with other sound waves. 

Ways to eliminate Noise pollution? 

 One way you can stop it, is like if you have loud music, or partying well you can just think of your Neighbors and just turn it down or just not have the party in the first place. Also you can just have the party somewhere else. For car noises, you can just not live next to a free way or next to a street. If a dog is barking and you get irritated just have the owner make sure she has her dog under control. 

Ways to help hearing loss? 

 A lot of doctor say that it is really hard to get you hearing back but some have very  weird and easy ways to get them back. For example, one doctor who i read about say that if you take vitamin pills then you can give energy to the cells in your ear that are dead then you may get better over the months or years, but you will never have you full hearing back. What i am hearing is that the pill solution is the most effective and will help you fast. 

So as you can see, noise pollution is one of the big three energy pollutions. So if i were you be very careful and aware of it.

The lab with toning forks

Tuning Fork Lab

Guiding question:
How does density of various solids affect the wave sound waves travel from the tuning fork?

Hypothesis:
I think that all the materials will have a different sound and a bigger frequency.
Data Analysis:

Material:	Density:	Observation:
Locker	7.85 g/cm 3	Tuning Fork 480 B: Very high pitched, proves that that the smaller they are the louder they sound. sound lasts for 17.69 seconds. a lot less vibration than with the larger one. Tuning Fork 256 C: lower pitched, sound is slightly harder to hear (not as loud) sound lasts for 15.03 seconds. a lot more vibration with this one than with the smaller one.
White Board	2.8 g/cm 3	Tuning Fork 480 B: less vibration lasts for only 9 seconds. Tuning Fork 256 C: loud! not as much vibration as with lockers. sound lasts for 18.65 seconds.
Desk	0.75 g/cm 3	Tuning Fork 480 B: Just as loud as it was against the locker, sound lasts for, 12.35 seconds. Tuning Fork 256 C: Sound lasts for 30.73 seconds, More vibration than on white board and lasts for longer.
Wall	3.12 g/cm 3	Tuning Fork 480 B: Lasts for 20.75 seconds, more vibration than other ones. lasts longer than dest Tuning Fork 256 C: Sound lasts for 34.0 seconds, not very high vibration.
Wooden Floor	0.50 g/cm 3	Tuning Fork 480 B: last for 9.44 seconds, same vibration amount as locker, very hollow sounding. Pitch lower Tuning Fork 256 C: Lasted 30.43 seconds, vibration not very high, pitch was high sounding.
Cement floor	3.12 g/cm 3	Tuning Fork 480 B: Lasts for 7.05 seconds, vibration high, pitch higher than mlst tries. Very loud, loudest one. Tuning Fork 256 C: Sound lasts for 27.25 seconds, vibration very high, higher than usually but not as high as last try.

Conclusion:

The bigger the fork the lower the pitch and the smaller it is the shorter it goes. The best sound we got from the both forks is from the locker. All related to the forks when you put them against you lips or put your finger in between the two metal things then your finger feels really weird and fuzzy.

Further Inquiry:

If i were to improve my lab then i would, try the fork on different items. I would also make more then one observation on one item. The things i did good, would be everything because i helped with everything and i was a good partner.

Properties of Sound!!!!!

Sound can come in Low and High frequencies and it can come in different intensities. The intensity of a sound wave is the amount of energy the wave carries per second through a unit area, that came right from the Science Explorer book. A sound wave with a bigger intensity will sound louder than a wave with lower intensity.
A sound that is lower than a normal person can hear is called Ultrasound. What i think that means is that Ultrasound is when dogs can hear it, like those special dog whistle.
When a sound wave goes toward the ear, the waves will go to the ear with high frequency. The pitch of the wave increases when it comes and that is called the Doppler affect.

Sound!!!!

Sound, sound starts with a vibration that later on ends up with a human being hearing. The way the sound goes through our ear is that. First the sound goes into the ear canal, then into the eardrum so that you get the frequency, then it goes through the stirrup and then into the anvil and in the anvil there are tiny hairs that sway when sound comes in and then the hairs send the sound to the brain.
The speed of sound depends on the Elasticity, if you dont know what Elasticity is, then i will tell you, Elasticity is the ability of a material to bounce back after being disturbed. Also in the speed there is density and temperature.
Density in a medium is how much matter, or mass there s in any amount of space or volume.

Earthquake safety plan!!!!

To make my house safe i would reinforce some of the shelves and i would do that to all the tables the closets and the the book shelves. Another thing i would do before i build the house i would make the construction workers build in metal that can move with the earthquake so that my house doesn't brake. I could also install these metal sheet so that when a earthquake come the sheets will go over the window so that they dont brake. But i would only do this if there was a earthquake like every week or month because if a earthquake happens every year or more then its just a wasnt of money well unless i am planning to stay there my whole life.
So now you know what i would do to my house for a earthquakes.
