For example, if the fundamental frequency is 600 Hz, the octave harmonic of this is 12, 000 Hertz (or 12 kHz) Harmonic frequencies are always louder than the fundamental. Physicians providing occupational health services to a company may supervise the hearing conservation program, review abnormal audiograms and advise the program administrator. Audiologists can test a greater number of frequencies and can measure air and bone conduction to confirm whether the loss is sensorineural, conductive or mixed.
