What is the formula for beat frequency?
f_b = |f_2 - f_1| is the formula for beat frequency
Two notes are sounding one of which is 370 Hz If a beat frequency of 5 Hz is heard what is the other note's frequency?
The other note's frequency would be either 365 Hz or 375 Hz. Since the beat frequency is the difference in frequencies between the two notes, you can either subtract or add the beat frequency to the known frequency to determine the other note's frequency.
Two whistles produce sounds of wavelength 3.4 m and 3.3 m. What is the beat frequency produced?
The beat frequency is the difference between the frequencies of the two whistles. Here, the beat frequency would be 1 / (3.4 m) - 1 / (3.3 m) = 1 Hz.
How can one determine the beat frequency in a given system?
To determine the beat frequency in a given system, you can calculate it by finding the difference between the frequencies of the two interacting waves. The beat frequency is the frequency at which the amplitude of the resulting wave oscillates.
Two notes are sounding one of which is 370 Hz. If a beat frequency of 5 Hz is heard what is the other notes frequency?
The other note's frequency would be either 365 Hz (370 - 5) or 375 Hz (370 + 5) depending on whether the beat frequency is the difference or the sum of the two frequencies.

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!
What should the beat frequency of two in-tunes instruments be?
The beat frequency of two in-tune Musical Instruments is zero.
What should the beat frequency of two in-tune instruments be?
The beat frequency of two in-tune musical instruments is zero.
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?
The beat frequency would be 6 Hz, which is the difference between the two overlapping frequencies (256 Hz - 250 Hz). This is the rate at which the intensity of the sound will oscillate, creating a pulsating effect.
Two notes are sounding one of which is 370 Hz. If a beat frequency of 5 Hz is heard what is the other notes frequency?
The other note's frequency would be either 365 Hz (370 - 5) or 375 Hz (370 + 5) depending on whether the beat frequency is the difference or the sum of the two frequencies.
How do you calculate the beat frequency?
The beat frequency is calculated by subtracting the frequencies of two sound waves. It represents the rate at which the amplitude of the resulting wave fluctuates.
What is the full form of BFO?
BFO=Beat Frequency Oscillator
