Choosing an audiometer depends on where it will be used and why. Occupational health screening and clinical diagnostic testing have different requirements, and a portable screening audiometer is not designed for the same job as a clinical unit.
What to weigh before deciding
- Screening or diagnosis
- Air conduction screening is usually enough for pre-employment and periodic examinations. Where diagnosis, follow-up and formal reporting are involved, you need bone conduction, masking and speech audiometry. Buying one step above current needs is cheaper than buying twice.
- Ambient noise and the booth
- Test validity depends directly on ambient noise, and a quiet room is often not quiet enough. A sound-isolated audiometric booth is what makes results defensible, particularly for screening carried out on a factory site or inside a mobile vehicle.
- Calibration obligations
- Audiometers must be calibrated at regular intervals, and a report produced by an out-of-calibration device causes problems during inspection. Settle the calibration interval, who performs it, and how long the device will be away, before you buy.
- Reporting and data transfer
- At high patient volumes, exporting the audiogram into software saves substantial time. Verify that the output format matches the occupational health or hospital system you already run.
Dentem supplies GSI Grason-Stadler and Maico audiometers along with audiometric booths, with installation, periodic calibration and repair handled by our own team. Tell us how many people you screen and where the testing happens, and we will size the configuration with you.
Frequently Asked Questions
How often should an audiometer be calibrated?
Established practice is a full calibration once a year. Three situations do not wait for that date: the device or headset has taken an impact, the headset has been changed, or results have shifted in a way nobody can explain. What an inspection asks for is a current calibration certificate, so tracking the date matters as much as running the device.
What is the difference between a screening and a clinical audiometer?
A screening audiometer measures air conduction pure tone thresholds at set frequencies, which is enough for workplace screening. A clinical audiometer adds bone conduction, masking and speech audiometry, so it can separate where and what kind of hearing loss is present. For occupational screening the screening device is the right choice; for diagnosis you need the clinical one.
Is a soundproof booth mandatory for audiometry?
In practice, yes. ISO 8253-1 sets the maximum permissible ambient noise for each test frequency, and an ordinary room sits above those figures. Without a booth a person tests worse than they hear, which is both clinically misleading and open to challenge at inspection.
Does changing the headset require recalibration?
Yes, and this is the step most often skipped. Calibration is done for the device and that specific pair of transducers together; a headset is not a standard interchangeable part. Results taken after fitting a spare headset, or after a headset returns from repair, are not valid until calibration is redone.
