: Professional standards usually use a red circle for right ear thresholds and a blue X for left ear thresholds. Advanced and Emerging Techniques

: Represents sound frequency (pitch), typically ranging from 125 Hz to 8,000 Hz . audiometry

Beyond conventional testing, several specialized methods have been developed to address specific diagnostic needs: : Professional standards usually use a red circle

: Evaluates how well an individual can hear and understand speech at different volume levels. Invented by Raymond Carhart in 1946, it is essential for determining how hearing loss impacts real-world communication. The Audiogram: Visualizing Hearing Invented by Raymond Carhart in 1946, it is

Diagnostic hearing tests, often broadly called "audiometry tests" or "audiograms," primarily consist of two main categories:

is the clinical technique used to identify and quantitatively determine the degree of hearing loss by measuring an individual's hearing sensitivity. It is the cornerstone of audiological health, providing the data necessary for medical treatments, hearing aid prescriptions, and assistive device fittings. Core Types of Audiometry

: Represents sound intensity, measured in decibels Hearing Level (dB HL) .
