4.44 minimum audible sound pressure level. Sound pressure level of a tone at the threshold of audibility that is presented by an earphone and measured or inferred at the tympanic membrane. Abbreviation, MAP; unit, decibel...
4.43 minimum audible field. Sound pressure level of a tone at the threshold of audibility measured in a free sound field for a subject listening with both ears and facing the sound source. The magnitude of the sound pressure level at the position to be...
4.42 hearing threshold level for pure tones. Hearing threshold of a given ear at a specified frequency and for a specified type of transducer when measured with an audiometer calibrated to reference equivalent threshold levels for air or bone conduction....
4.41 hearing screening. A component of an audiological test program that attempts to determine which individuals of a total population may have a hearing problem and therefore require further audiological...
