Brainstorm five things that would be very low in decibels and another five things that would be high in decibels. Estimate how many decibels each would be. One example for a low frequency sound might be a fog horn at 175 Hz. From reading the results of an audiogram, audiologists can also determine what type of hearing loss has occurred. Conductive hearing loss occurs when the outer or middle ear doesn't work properly.
Common causes are too much fluid in the middle ear or too much ear wax.
Conductive hearing loss is usually treatable. Sensorineural hearing loss occurs when the inner ear or hearing nerve becomes damaged. This happens with aging or damage from loud noises. The audiogram shown in Diagram A represents the charts of typical conductive and sensorineural hearing losses. The areas above the lines are sounds that the person would not hear.
