Pure-tone audiometry provides ear specific thresholds, and uses frequency specific pure tones to give place specific responses, so that the configuration of a hearing loss can be identified. As pure-tone audiometry uses both air and bone conduction audiometry, the type of loss can also be identified via the air-bone gap .

There are two versions of TODS: TODS-CR (clinician-rated) and TODS-PR (parent-rated). Each version is a 15-item scale that helps clinicians evaluate the severity of symptoms that may be associated with tics—inattention, hyperactivity, obsessions, compulsions, aggression and mood disturbances. [2]
The Yale Global Tic Severity Scale (YGTSS) is a psychological measure designed to assess the severity and frequency of symptoms of disorders such as tic disorder, Tourette syndrome, and obsessive-compulsive disorder, in children and adolescents between ages 6 and 17. [1] [2]
A tone at the frequency of 4000 Hz is presented for 60 seconds at an intensity of 5 decibels above the patient's absolute threshold of hearing. If the patient stops hearing the tone before 60 seconds, the intensity level is increased by another 5 decibels with the procedure repeated until the tone can be heard for the full 60 seconds or until no decibel level can be found where the tone can be ...
"Conventional" pure tone audiometry (testing frequencies up to 8 kHz) is the basic measure of hearing status. [6] For research purposes, or early diagnosis of age-related hearing loss , ultra-high frequency audiograms (up to 20 kHz), requiring special audiometer calibration and headphones, can be measured.

Normal or subnormal hearing: average tone loss is equal or below 20 dB HL; Mild hearing loss: average tone loss between 21 and 40 dB HL; Moderate hearing loss First degree: average tone loss between 41 and 55 dB HL; Second degree: average tone loss between 56 and 70 dB HL; Severe hearing loss First degree: average tone loss between 71 and 80 dB HL
