Sound Level Meter
Device for measuring the intensity level of sound waves in air; the
unit of measurement is in decibels sound pressure level (SPL dB).

Tympanometry (Tymp)
Procedure used in the assessment of middle ear function in which
the immittance of the tympanic membrane and middle ear is meas-
ured as air pressure delivered to the ear canal is varied.

Transducer
Electronic component transforming e.g. an electrical signal into
sound, sound into an electrical signal, or a pressure into a voltage.

Tone
Sinusoid or steady-state (ongoing) sound of a single-frequency (vs.
noise with many frequencies or a click).
noise with many frequencies or a click).
Tone Burst
Evoked Response Audiometry (ERA) is an electrical response to
acoustical stimulus, usually a Click or a Tone Burst. A Tone Burst is
a sinusoid or steady-state (ongoing) sound of a single-frequency (vs.
noise with many frequencies or a click). Tone bursts can be defined
by 4 parameters: RiseTime, DecayTime, Duration and StimDelay.
