Explain how sound waves stimulate the hair cells of the spiral organ of corti to cause hearing?
When the sound waves stimulate the hair cells of the spiral organ of corti to cause hearing, the impulses are usually sent to the brain.
-- Most of the Marseillaise
-- Most of "Oh Canada"
-- Most of the Venezuelan national Anthem
-- Most of the Turkish national anthem
-- All of "Hatikvah", the Israeli national anthem, as well as the closely-related
background theme that runs through Smetana's "The Moldau".
-- The opening theme of Bach's Brandenburg Concerto #5
-- The main theme from the final section, titled "The Great Gate of Kiev",
from Mussorgsky's "Pictures at an Exhibition".
-- The German national anthem, "Das Deutschlandlied".
-- "Rock Around the Clock"
-- "When the Saint Go Marchin' In"
-- If the highest and lowest glass are not tuned to two octaves of the same
note, then you can play the Star Spangled Banner with 8 of them.
You can NOT do the scherzo from Litolff's 'Concerto Symphonique', or anything
from Berlioz' 'Symphonie Fantastique'. You should not even try them, lest you
hurt yourself.
How is analogue recording made?
They etch the sound waves on the discs with the frequencies and amplitudes. For example the gramophone disc. Its huge and has a lot of circular discs spiraling towards the center. Originally the person sings in the mic and the waves move the carving tool in the similar pattern it itself is moving and makes grooves and cuts on the discs - deeper cuts for higher amplitude regions while shallower in the less amplitude regions.
So when you play it the pin passes though these grooves and relays the information through its body into the loudspeaker which amplifies the sound enough for us to hear it.
Nothing remotely exciting. The pitch of your voice will be normal because there is no helium passing your vocal cords. CO2 is exhaled in every breath and will be mixed with the helium as it would be in other atmospheres.
Only if you remain in the room and continue to breath the helium will there be any ill effects. Helium isn't poisonous but the lack of oxygen would cause asphyxiation and eventually death.
What is units measuring the intensity of a sound wave?
The intensities of traveling waves, which includes sound, light, etc., are measured in units of power divided by area. That is, watts per square meter (W/m2 ) or watts per square foot (W/ft2), or any combination of units which is equivalent.
Is there any relationship between sound frequency and sound absorption?
Yes - the amount of absorption can depend on the frequency.
What device uses sound waves and transforms them into mechanical energy to make recordings?
Sound waves are transformed into mechanical energy to make recordings by the use of a phonograph. The earliest recording devices of this type were hollow cylinders with tiny holes in them.
Does a piano make sounds with a large range of frequencies?
A typical piano has a range of at least 7 octaves; for comparison, the range of human hearing is about 10 octaves.
Where can one purchase a Bose Sound Wave?
There are many places one might go to purchase a Bose Sound Wave. In addition to the official Bose brand website, one might also try the Amazon website.
What is the principle of Ultrasonic soldering?
Heat is the movement of molecules, Sound is the movement of molecules. Thus with proper application, the energy of sound can be converted into heat.
What we hear as pitch is related mostly to?
To the sound's frequency - how many vibrations per second it has.
How does the wavelength of a G-note sound wave compare to the wavelength of an A-note sound wave?
Assuming that both notes are in the range of C4 (middle C) and C5, G has a frequency of 392Hz, and A has a frequency of 440Hz. Assuming that both sound waves are travelling through air, through which sound travels at 340ms-1, then the wavelengths for G and A can be found to be 0.87m and 0.77m, respectively.
An easier way to assess a change in wavelength would be to look at the equation v=fλ, where v is the speed of sound, f is the frequency of the note, and λ is the wavelength of the note. A higher pitch note means a higher frequency, and since the speed of sound is constant, then if the pitch is increased the wavelength must compensate by decreasing.
Simply put, higher pitch means smaller wavelength.
Is it possible for a 440 hz sound wave to be louder than an 880 hz sound wave?
Absolutely
440 Hz is the frequency of the A note that is 1½ steps below middle C, the top line of the bass clef. 880 Hz is the frequency of the A note one octave higher, the second space from the bottom of the treble clef. On a piano, if you slam hard on the lower of those two A keys and just lightly press the higher one, the 440-Hz sound will be louder than the 880-Hz sound.
The loudness, or amplitude, of a sound wave has to do with how tightly the air molecules (or the molecules of whatever the sound-propagating medium is) are packed in each wave of the sound, while the sound's frequency or pitch has to do with how frequently the waves are generated (440 times per second in the case of a 440-Hz sound), or how far apart the waves are (frequency is inversely proportional to wavelength).
The permanent one is damage to the cochlea. Artificial implants are now available though.
How do animals produce transmit and receive sound?
How is music affected in an auditorium when there is destructive interference of sound waves?
Destructive interference is where two sound waves mix and cancel each other out to some extent. If destructive interference is occurring, the sound level will be lower than you would otherwise expect. A properly designed auditorium will use both destructive and constructive interference where required to achieve the desired clarity of sound.
The medium through which sound waves travel affects the what?
Sound travels the fastest through dense materials, since sound is simply the transfer of kinetic energy between matter. Thus a more dense object creates faster sound waves.
What happens when you try to walk on a smooth polish surface wearingbrand new shoes?
Depends on the surface of your sole on the shoe. Polished leather or rough rubber-sole! Leather: You slip. Rubber brobably make marks on the surface
When you hear yourself talk, most of the sound that you hear passed through the bones of the skull, not the air. These bones have resonances and act as filters changing the sound that arrives at your ears.
When you hear yourself talk on a recording the sound passed through the air and is unfiltered, this is what other people hear when you talk
So in fact you sound normal on the recording (as others hear you) and wierd when you just hear yourself directly. You just aren't used to hearing how you really sound.
