What is the beat frequency when a 494 Hz tuning fork and a 499 Hz tuning fork are sounded together?

The beats are the sum and difference of the components ... (A + B) and (A - B).
If something really non-linear is also going on, you also get (2A - B), but we'll
leave that alone for right now.
That pair of forks produces beats at 2 Hz and 990Hz .

∙ 14y agoThere should be two beat products ... one at 990Hz and another at 2 Hz.

∙ 12y agoThere are 2 frequencys. One is 990, and the other is 2. I would say go with 2 Hz.

That's the beat frequency . . . 5 Hz .

What beat frequency is produced by two tuning forks that vibrate simultaneously withe frequencies?
3.0 HZ
What frequency would you hear with a 340 Hz tuning fork near a guitar string vibrating at 350 Hz?
340 hz is the pitch or note that is sounding. It's the times the string would vibrate per second. By 350 hz guitar, I would get you would be playing a note on the low E string and it would sound sharp to the tuning fork. You would hear a subtle beat or pulsing when sounded together. That beat would get slower and slower as you loosened the string to bring the pitch down until it quit altogether. Your would then have that note tuned to 340 hz. BTW...standard tuning is called A440 meaning that the A note is tuned to 440hz.
Two tuning forks struck at the same time one tuning fork has a frequency of 20 hz while the second tuning fork has a frequency of 226 hz how many beats will result?
Number of beats heard in one second will be got by the difference between the parent frequencies. Hope you have given wrong data for parent frequencies. The first one has to be 220 Hz and the other is 226 Hz. Hence 6 beats will be heard in one second. If you say 20 is the right one then difference will be 206. If 206 beats get produced in one second it will not be named as beat at all. Moreover our hearing could not recognize this as beating at all. So better correct the given data.
Do piano tuners listen to the beat frequency between their tuning fork and the wire they are tuning?
Yes, they do. When the tuning fork (or the more modern electronic tone generator) is providing a reference tone, the tuner will strike a key and listen for a beat frequency between the reference and the piano string. With wrench in hand, the person tuning the instrument will take a bit of tension off the string, and will then increase the tension to bring the piano string "up" and equal to the frequency of the reference. The beat frequency will disappear as the tones become equal in frequency. It is the practice of the individuals tuning a piano to always bring a string of the instrument "up" to the frequency of the reference rather than "detuning" the string to lower the pitch and match it with the reference. With a bit of practice and patience ('cause you can always detune the string and "start over" to get it spot on), you can generally do a pretty good job of tuning the piano, though the professionals have been doing it for many years. These experienced folks have a good "ear" for the beat frequencies. The electronic references are modestly priced now, thanks to 21st century electronics. Note that there are cool electronic tuning units that will "listen" to the beat frequency and indicate to you when it disappears and a match has occurred. Our ears are generally fairly sensitive to the difference in the frequencies of two tones. When the tones "beat" on one another because they are being generated simultaneously, the difference between them is usually fairly obvious. Oh, and you are listening to the interference frequency between the two tones, which is what the beat frequency is. Certainly it's a bit of a challenge to accurately tune a piano, but many folks are fairly capable of doing it and only need a modicum of practice. Leave that big Steinway or Yamaha to the experts, but if you've got an old upright, have a go!
A tuning fork of frequency 256Hz is vibrating near another tuning fork A beat pattern of frequency 6.6Hz is produced What can you say about the frequency of the second tuning fork?
Sounding two tuning forks at once will not give you one frequency. The "sound" that you hear will be a harmonic combination of the two frequencies. However because of acoustics the higher one (266Hz) will seem more prominent than the other.
How do beats help determine whether two sound waves are the same frequency?
A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.
How are beats useful in tuning musical instruments?
By tuning musical instrument we mean that to produce a note of Desired frequency. Take a standard musical instrument of well defined frequency. The new musical instrument and the standard instrument are sounded together. Initially we will hear mixed sound due to slightly frequency difference between them. The frequency of the musical instrument is gradually adjusted till we will hear same sound. When this happens, the musical instrument Will produce the note of desired frequency and is said to be turned. In this way, beats become useful in tuning a musical instrument.

How could you use beats to match one frequency to another frequency?
A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.

Four beats per second are heard when two notes are sounded The frequency of one note is 420 Hz what is a possible frequency of the other note?
The beat frequency is the difference of the overlapped frequencies. Thus the other frequency is either 445 or 435 Hz. For detail, read the wikipedia page on Beat(acoustics)

What is the formula for beat frequency?
f_b = |f_2 - f_1| is the formula for beat frequency
Ames hears a 2 Hz beat frequency while tuning his trumpet with another trumpet player What could cause this beat frequency?
The frequencies of the two trumpets could be 2 Hz different, and the boys could be blasting it so loud that the amplitude response of Ames' poor ears is in the non-linear region and the mix products are being generated in his poor cochlea.
What should the beat frequency of two in-tunes instruments be?
The beat frequency of two in-tune Musical Instruments is zero.
