Audiocups

Noise-reducing enclosures

Industry-leading audiometric enclosures, designed to ensure 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.

  • Industry leading attenuation levels
  • Allows audiometry to be completed in high ambient noise
  • Invaluable when an audiology booth is not available
  • Additional attenuation when an audiology booth is available
  • Articulated suspension of the earphone provides an accurate and comfortable fit
  • Easily fitted to any TDH 39 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

  • 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.

     

    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.

  • 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.
