The digital portable audiometer 9910 by Quirumed allows to establish
a definitive diagnosis of the hearing impairment.
It offers a patient response button and 2 back lit LCD displays.
For the measurement one can begin with an intensity of 40 db and a frequency of 1000hz.
Decrease the tone in steps until the patient can no longer hear the pitch, and read this value.
It can be used in audiometry cabins,
with frequency range from 125-8000 Hz
and intensity from -10 dB to 100 dB.
And it with works with a AC adapter.
The device itself will alert you when it reaches 100db
as a high-output tone may cause discomfort to the patient.
Along with the digital audiometer 9910 are included:
high noise isolation headphones, an AC adapter,
a patient response button, a carrying case
and a user manual in French, English and Spanish.
