In the US, the current frequency is 60 Hz tone. The 60 Hz tone is almost exactly halfway between A♯ (58.24 Hz) and B (61.68 Hz). However, the 60 Hz frequency is pretty much only used in the Americas (mostly), Saudi Arabia, South Korea, the Philippines and about half of Japan.

What is the frequency of C note?
Historically, concert pitch has varied. For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies).
What causes 60hz noise?
Ground loop noise is typically a 50/60 Hz spike and is caused when the different components of the system have a different ground potential. This potential difference causes current flow between the components, which is then amplified through the amplifier and sent to the shaker.
How do you find the frequency of a note?
Starting at any note the frequency to other notes may be calculated from its frequency by: Freq = note x 2 N/12, where N is the number of notes away from the starting note.

Can humans hear 50 Hz?
The standard hearing capacity of the people ranges between 20Hz to 20,000Hz of frequencies, the normal hearing range is about 1000Hz to 5,000 Hz, which is a human speech sound.At very low frequencies like 50Hz, a human ear cannot accept the sound. It is a very low frequency which can be heard only by a few animals.
How low Hz can humans hear?
about 20 Hz
For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz.
How do I get rid of 60Hz hum?
How Do I Get Rid of It? When it comes to ground loops, the easiest way to get rid of the humming noise is to simply power everything via a single AC socket. This can be achieved by using a single power strip or surge protector that plugs into the wall. Et voila, problem solved.
What Hz is B?
approximately 493.883 Hz
When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of Middle B (B4) is approximately 493.883 Hz. See pitch (music) for a discussion of historical variations in frequency.
What note is 262 Hz?

How can I stop my transformer from humming?
Use Acoustical Dampening Material
You can reduce some of the noise generated by an electrical transformer by using materials that prevent the sound from spreading. Covering the walls of the transformer room with absorbent materials such as kimsul, acoustical tile or fiberglass may help keep the noise contained.
Why do I hear a vibrating sound in my house?
Some possible reasons why you might hear a vibrating or humming noise coming from a wall include: The connections inside an electrical outlet or switch could be going bad. The screws that fasten the wires to the outlet or switch might be loose.A half-opened air vent on the wall may be buzzing due to high air pressure.
How do you get rid of 50 60 Hz?
Powerline interference (50 or 60 Hz noise from mains supply) can be removed by using a notch filter of 50 or 60 Hz cut-off frequency. EMG noise is a high frequency noise of above 100 Hz and hence may be removed by a low-pass filter of an appropriate cut-off frequency.
