Audiocups
Noise-reducing enclosures
Industry-leading audiometric enclosures, designed to assist with accurate pure tone hearing screening in conditions where ambient noise is too high for unshielded earphones.
The perfect add-on to a standard air conduction headset such as the RadioEar DD45, Telephonics TDH39 and TDH49 transducer. Easily retrofitted in the field without the need for recalibrating your audiometer.
Please note: image shows complete headset option with fitted transducers.
Performance
Our noise-reducing enclosures are designed to provide unique noise attenuation to assist in accurate audiometry measurements when compared to standard audiometry headsets. Audiometry threshold measurements should be recorded in accordance to the maximum stated ambient noise levels advised in ISO 8253-1:2010.
Key features
- Industry leading attenuation, designed to minimise external noise
- Suitable for environments where ambient noise may affect test accuracy
- Lightweight, adjustable and ergonomically designed for an accurate and comfortable fit
- Articulated suspension of the earphone provides an accurate and comfortable fit
- Easily fitted to any RadioEar DD45, Telephonics TDH39 and TDH49 type earphone
- No requirement to recalibrate after fitting
Considered design
Unlike supra aural headphones which provide a minimal degree of attenuation, our headphones are designed to add additional attenuation using circumaural, dampened ear cushions.
Incorporating a fully articulated earphone suspension system also ensures earphone cushions are able to locate against pinnas of all shapes, without obstructing the ear canal. Whilst also enclosing the external ear to exclude background noise.

Frequently asked questions
Can I use the Audiocups with my audiometric headphones?
Our audiometric headphones are designed to be easily fitted to a fully articulated earphone suspension systems in the field. The rework takes less than five minutes and does not require a recalibration of your audiometer, so you can continue your audiometry session straight after. Watch our video on how to change the headset on your audiometry headphone.
Why is a silent environment critical for hearing testing?
When testing someone’s hearing, sounds at a very low intensity are presented to identify the hearing threshold of a patient. If the test environment is filled with other sounds such as car noises, conversations, machines noises (e.g. production or coffee machine), this will distract the test subject from the actual task. It is difficult to identify very soft sinusoid sounds in a noisy environment. Learn more about the impact of background noise on industrial screening results.
Why should I use headphone covers?
Ear cushions can serve as potential carriers of micro-organisms from the air, skin contact and draining ears (Bankaitis, 20111), since there is direct contact of the pinnae (outer ear) with the headset ear cushions.
Disposable covers which can be slipped over the ear cushion create a barrier between the pinnae and the headset ear cushion and are therefore highly recommended to be used with every patient. Learn more about how to keep your audiometry equipment clean.
