Pure-tone audiometry

Pure-tone testing is a standard test to measure the hearing range in each ear by finding the quietest sound the ear can detect at different pitches and volume.


Real ear measurement

Sometimes can be called a probe microphone measurement. This is a method of assessing sound pressure levels in the ear canal using a calibrated probe tube.

Bone conduction

A bone conduction audiometry test helps an audiologist to determine if there is a problem in the outer or middle ear, generally known as conductive hearing loss.

Audiometric masking

Audiometric Masking is performed to provide accurate results of Pure Tone Audiometry by separating the ears acoustically. This means that the non-test ear is exposed to a masking noise and therefore is unable to assist the test ear.

Auto-Hughson westlake

Primus Pro offers automatized Hughson-Westlake audiometry and can be used as a screening tool for adult patients.

Speech audiometry

A speech audiometry test is used to assess a client’s ability to recognize speech in a variety of situations. People who have hearing loss say that hearing speech is the most troubling area.

Speech-in-noise (SIN)

More advanced speech testing takes into account how speech is understood in the presence of noise. A series of words are played, accompanied by various noise types.

Quick speech in noise

The QuickSIN is a speech-in-noise test that quickly and easily measures the ability to hear in noise. The QuickSIN test should be used on all adult patients as part of the audiometric test battery.

Primus Pro offers the classic Weber test using a bone conductor transducer. The Weber test is suitable for quick screening for unilateral conductive or sensorineural hearing loss."

TEN test

The Threshold Equalizing Noise (TEN) test is used to identify dead regions in the cochlea. The TEN signal masks hair cells that may pick up the pure tone signal adjacent to the dead region.

SISI is a test intended to recognise 1dB increases in intensity during a series of pure tone bursts. This was designed to assist in the determination of where the hearing impairment arose from.

Free Field

Free Field Audiometry provides the clinic an option for assessing individuals unable to wear headphones of any description. This is mostly paediatric and additional needs population.
