Pure Tone Audiometry (PTA)
This is a basic hearing test conducted on everyone who reports hearing loss. Often it is important to perform PTA for people who work in call centers and professions which require staying in a noisy environment for long hours every day. There are two tests that have to be performed as part of PTA, i.e. AC (Air Conduction) and BC (Bone Conduction). It is used for diagnosis of conductive hearing loss (middle ear infection, sensorineural hearing loss, as well as mixed hearing loss.
PTA is important to rule out issues such as ear infection, hearing disability, vertigo, and ear blockage while also identifying the degree of hearing loss.
