Why is there a high pitch sound in the office? What could have caused it n how to stop it?
I constantly hear this high-pitch sound, on and off in the office. Sometimes long ones (1-2sec), sometimes short (half a sec).
I hear from colleagues that it could be coming out from some electrical appliance. But what is it?? n there are so many electrical appliance in the office.
Fluorescent lights operate at high frequencies. Malfunctioning ballasts could cause it to be audible on occasions.
Very High Pitch Sound!
