What is the intensity level of probe tone in tympanometry?

In tympanometry, the intensity level of the probe tone typically ranges from 226 Hz for adults and 1000 Hz for children. This probe tone is used to assess the mobility of the tympanic membrane and middle ear function by measuring the acoustic admittance as the pressure in the ear canal is varied. The intensity level is generally set at a safe volume to ensure accurate measurement without discomfort to the patient.
