What would the beat frequency be if you added tones of 880 Hz and 882 Hz?

The number of beats that we hear per second is the beat frequency. It is equal to the difference in the frequencies of the two notes. In this case: Beat frequency = 882 Hz - 880 Hz = 2 Hz. This means that we will hear the sound getting louder and softer 2 times per second.

What is the formula for beat frequency?
f_b = |f_2 - f_1| is the formula for beat frequency
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.
What is the beat frequency sensible for human ear?

How could you use beats to match one frequency to another frequency?

When low frequency signals added to high frequency signal then the envelope signal will follow which signal?
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
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!

When a sound wave with a frequency of 256 Hz overlaps with a sound wave with a frequency of 250 Hz what would the frequency of the beats be?
There should be two beat frequencies produced: 506 Hz and 6 Hz.
