Audiometer Buying Guide for ENT Clinics and Hospitals
Audiometers are essential in ENT clinics, audiology centres and occupational health. Here is how to choose one.
Screening vs diagnostic
- Screening audiometers: basic air-conduction tones.

Why two channels matter
Two independent channels allow proper masking and comparison tests, which are essential for accurate diagnosis in asymmetric hearing loss.
Room requirements
A sound-treated booth or quiet room keeps ambient noise within acceptable limits.
Calibration
Calibrate at installation and periodically after that. Stable digital circuits reduce drift, but scheduled calibration is still important.
