Sound Waves

Sound waves are a mechanical oscillation of pressure. It is a series of vibrations that can be heard.

Why does everyone hate the sound of their own recorded voice?

User Avatar
When you breath small vibrations in your cartilage create sound that you cant hear, these sounds are recorded on speakers. when the sound is emitted from the speaker it cancels out the same sound played back in a phenomenon called the reflex effect. because the sound waves are slightly distorted when they reach the speaker some of the inaudible sounds clash. other people don't hear the sounds because the sound travels through your sinuses. the clash of sounds makes a voice seem dry to the owner.

The lowest frequecy note of an organ is 16.4 Hz. What is the length of the shortest open organ pipe that will resonate at this frequency?

Scroll down to related links and look for "Closed or Gedackt Organ Pipes - Wikipedia". Organ builders still tend to use feet rather than metres when dealing with organ pipe length and tone e.g. an 8 foot pitched pipe is the same pitch as a piano, and is called '8 foot' because the longest pipe of the rank at this pitch ( the C below the C below Middle C) is 8 feet long. A 4-foot pipe is an octave higher, a 2 foot 2 octaves higher, and a 16 foot rank an octave lower than piano pitch. The fundamental tone of 16.4 Hz represents a 32-foot organ pipe, which is found, except in the very largest organs, only in the pedal section of large instruments. Although the 32 foot pitch is found frequently on large instruments (like cathedral organs) it is not the deepest note of an organ as stated in the question. Some organs, such as the Atlantic City Auditorium organ, USA and Liverpool Cathedral Organ in the UK have 64-foot ranks giving the lowest note as 8.2 Hz. On most organs offering 64-foot ranks, the sound is either produced by a stopped 32-foot pipe, or acoustically, where two shorter pipes are tuned so that the beats between them produce a 64-foot tone. Many huge organs do have a 64' rank (usually called gravissima), but nearly all of them are produced by either a stopped 32' or acoustically. There are not more then 5 organs that has a true (not acoustic, stopped, nor digital), (only counting the rank(S) that accually goes down to the sub-sub-contra C) 64 foot rank, three of them are the organ at the Atlantic City Convention Hall Main Auditorium, the organ at Sydney City Hall, and the one at Worcester Cathedral, in UK. The shortest lengh that will produce 16.4Hz (CCCC) is 16 ft, although this note is the C of the sub-contra octave, this 16ft pipe is stopped on the top, so it produces the note that corresponds to twice that lengh(32ft) . Also should be mentioned, the lowest (true) note on an acual organ is CCCCC which is 8 Hz, that single note cannot be heard alone. THE lowest note is produced by either stopping the 64' or combining the 64' and the fifth(42 2/3) to produce a 128' CCCCCC which is 4 Hz. The lowest note is produced by combinding a stopped 64' ( 128') and stopped 42 2/3' (85 1/3') to produce a resultant 256' which is 2Hz on CCC CCC C, this note is not considered audible by the human ear

What happens to the amplitude when loudness increases?

User Avatar
Amplitude = "Loudness" In that a direct increase in amplitude will cause the sound to be "louder".

Why does the music coming from a marching band in a spread out formation on a football field sometimes sound discordant?

User Avatar
because sound travels pretty slow. thats why if your in the very back at a rock concert, and you see the drummer hit a drum, and you hear the drum a half a second or so later. in marching band, you want the sound to line up for the audience. to achieve this, listen back, and center. usually the drumline. if your in the audience and it sound discordant, its not your fault.

Does the whistle of a tea kettle have greater frequency than a drum beat?

User Avatar
Yes it does. Higher pitched sounds have higher frequencies than lower pitched sounds.
Asked in Sound Waves

What happens to sound waves when the source of the sound is moving away from you?

User Avatar
The pitch becomes lower because the sound waves are no longer compressed once the source passes you.
Asked in Sound Waves

What is the difference between sound waves and ultrasound waves?

User Avatar
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit

What happens when the intensity of a sound decreases?

User Avatar
That means that it gets weaker.In physics, intensity is defined as power per unit area.
