The pure-tone audiometry, including air- and bone-conduction testing, is conducted to characterize type, degree (severity), and sidedness (unilateral or bilateral) of hearing loss. Clinically, pure-tone hearing thresholds (lowest decibel hearing level [dB HL] at which the patient detects the pure tone at least 50% of the time) at frequencies from 250 to 8000 Hz, important …

https://pubmed.ncbi.nlm.nih.gov/24042555/
In a study with a high directness of evidence, a high risk of bias, and a low prevalence of otosclerosis (8%) in patients with conductive hearing loss, the presence of a Carhart notch at 2000 Hz increased the risk of otosclerosis with 33%. In a second study with moderate directness of evidence, moderate risk of bias, and a high prevalence of otosclerosis (72%) in patients with …

https://pubmed.ncbi.nlm.nih.gov/32609044/
No- or low-touch audiological assessment outside a sound-booth precludes test batteries including bone conduction audiometry. This study investigated whether conductive hearing loss (CHL) can be differentiated from sensorineural hearing loss (SNHL) using pure-tone air conduction audiometry and a digits-in-noise (DIN) test.

Disorders of hearing can be conveniently divided into conductive, sensorineural, and mixed hearing loss based on pure-tone audiometry, where conductive hearing loss occurs if there are impediments to conveyance of sound through the external and middle ears to the cochlea (eg, impacted cerumen, middle ear effusion) and sensorineural hearing loss results …

Pure tone audiometry is the mainstay of investigations for hearing loss. It can confirm the presence of hearing loss, quantify the severity, and determine the nature of the hearing loss.[21] Headphones deliver sounds in varying loudness over 250 to 8000 Hz. The patient notifies the audiologist when they hear the sounds 50% of the time.

PTA or pure tone audiometry is a hearing test accepted worldwide as a standard protocol for determining hearing levels or hearing loss. Prerequisites for this test: -> The individual undergoing this test should be 8 years and above. -> PTA should be done in an acoustically treated room with least noise interference.

A pure tone average refers to the average of hearing threshold levels at frequencies 500, 1000, 2000, and 4000 HZ in air conduction curve. PTA determines the type and degree of hearing loss. According to Clark (1981), the degree of hearing loss was classified as follows [10]: 1. Minimal (15-25) 2. Mild (26-40) 3. Moderate (41-55) 4.
