Almost the same frequency and are sounded together.

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.

The size of the increase between two tuning forks refers to the difference in their frequencies, which is usually measured in hertz (Hz). For example, if one tuning fork vibrates at 440 Hz and another at 450 Hz, the increase between them is 10 Hz. This difference can impact the perceived pitch and harmonics when both forks are struck together.

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.

Beats in sound occur when two sound waves of slightly different frequencies interfere with each other, creating a pulsating effect of loud and soft sounds. This is because the waves temporarily reinforce and cancel each other out as they overlap in space. Beats are commonly heard when tuning musical instruments or from the interference between two close frequencies.
When you strike two tuning forks of different frequencies simultaneously, they will produce a phenomenon called "beats." This occurs because the sound waves from each fork interact, creating alternating periods of constructive and destructive interference. As a result, you will hear a fluctuating sound, where the intensity of the combined sound increases and decreases at a rate equal to the difference in their frequencies. This creates a rich auditory experience, highlighting the unique characteristics of each fork while also demonstrating the principles of wave interference.

Beats help in tuning instruments by creating a rhythmic interference pattern that occurs when two sounds of slightly different frequencies are played together. For example, when tuning a guitar, piano, or violin, you can listen for the beats produced when a reference pitch is played alongside the string being tuned. As the pitches get closer in frequency, the beats will slow down and eventually disappear, indicating that the instrument is in tune. This method allows for precise tuning by ear, ensuring that the instrument produces harmonious sounds.
