the use of specialized calibrated equipment; sound-proofing of the room where hearing test is held; heterogeneity of parameters of sound-recording systems in smartphones and tablets, and also headphones or headsets; noise masking effect of tone signals [1]
Audiometry (from Latin audīre 'to hear' and metria 'to measure') is a branch of audiology and the science of measuring hearing acuity for variations in sound intensity and pitch and for tonal purity, involving thresholds and differing frequencies. [1]
WS Audiology (formerly Sivantos Group and Widex) is a privately-owned manufacturer of hearing aids with headquarters in Denmark and Singapore with roots going back to 1878 and Siemens AG. [1] The current company was created following the 2019 merger of Sivantos Group and Widex . [ 3 ]
Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss.
