Testing the human ear's capacity to hear, understand and record sounds "Audiometry".
Audiometry from the Latin audire, "to hear", metria, "to measure") is the science of measuring hearing acuity for a range of sound intensity, pitch and tonal purity, involving various thresholds and differing frequencies. Typically carried out using an audiometer (calibrated annually) which has the capacity of producing a range of pure tonal sounds as well as warble tone, speech weighted noise, white noise and others.

In the United Kingdom the measuring of a persons hearing thresholds are based upon the British Society of Audiology (BSA) Procedures "Pure Tone Air and Bone Conduction Threshold Audiometry with and without Masking" 2007 with amendments and minor corrections in February 2012. The latest version of the complete tests and procedures was published by the Society in August 2018 next due for update in 2023, a link to this is shown below.

Important: If you believe that you suffer from Tinnitus you should tell the person who is to carry out your audio metric test; and they should then offer to test you using a "Warble" sound, a sound which should be easier for you to identify through your Tinnitus. As well as this; the tester will vary the time interval between presentations so that you are unable to guess when the next presentation is to occur.

These audiometric results can be supplemented by the additional use of uncomfortable loudness levels as described in the BSA Procedure "Determination of Uncomfortable Loudness Levels" published in June 2019
As well as the above, clinicians may also carry out tests to establish the response of the tympanic membrane to pressure and vacuum changes called Tympanometry. The BSA recommended procedures are defined under "Recommended Procedure for Tympanometry" published 1992 were amended bringing the procedures up to date, in the autumn of 2013 and these amended procedures are next due to be reviewed in 2018. No update issued as of April 2020.
The BSA procedure for examination of the Human Ear "Otoscopy" is covered by the BSA Procedure "Recommended Procedure for Ear Examination" published 2010 and is current. Although due for review in 2015 these procedures are still current as of April 2020.
Below are a series of published on the world wide web videos which show these procedures in depth.
