Audiocups

Noise-reducing enclosures

Industry-leading audiometric enclosures designed to ensure accurate pure tone screening audiometry testing in conditions where ambient noise becomes too high for unshielded earphones.

Our Audiocups are the perfect add-on to a standard air conduction headset such as the RadioEar DD45, Telephonics TDH39 and TDH49 transducer and are easily retrofitted in the field without the need for recalibrating your audiometer.

Consisting of a headband, a cup for each ear side dampened with foam and a spring for the headset transducer to be fitted, the headset allows the transducers inside the cups to fit with any ear shape without obstructing the ear canal.

Performance

These 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.

Considered design

It’s not always possible to conduct audiometry in a perfect testing environment (ISO 8253, ANSI S3.1-1991). This is often the case when screening audiometry is performed, e.g. while traveling or in local set-ups.

In these situations, supra aural headphones allow a minimal degree of attenuation and surrounding noise might impact the hearing of the patient negatively. Our headphones are designed to build on the existing attenuation of the audiometric headphones used and add additional attenuation by using circumaural, dampened ear cushions.

Incorporating a fully articulated earphone suspension system ensures that earphone cushions are able to locate against pinnas of all shapes, while at the same time Audiocup cushions enclose 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 lead on your audiometry headphone here.

    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.

  • 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.
