What are Different Types of Hearing Tests (Audiometry)? A Comprehensive Guide

Hearing is an essential part of how we interact with the world around us. It allows us to engage in meaningful conversations, enjoy music, and share laughter with loved ones. When our hearing begins to decline, it can significantly impact our quality of life. Hearing tests are vital diagnostic tools that assess hearing ability and identify issues early, helping preserve your auditory health.

In this blog, we’ll cover the different types of hearing tests, how they work, and what their results mean. Understanding these tests can empower you to take control of your hearing health.

 

What Are Hearing Tests?

Hearing tests are assessments designed to measure a person’s ability to detect sounds at different pitches and volumes. They help hearing care specialists pinpoint the type and severity of hearing loss, enabling them to recommend effective solutions such as medical treatments or hearing aids.

Hearing tests are critical for:

  • Identifying hearing loss early.
  • Monitoring changes in hearing over time.
  • Determining the need for assistive devices like hearing aids.

 

Types of Hearing Tests

There are several types of hearing tests, each designed to evaluate a specific aspect of hearing. Here’s a closer look at the most common ones:

  1. Pure-Tone Audiometry
    This is one of the most commonly used hearing tests, measuring a person’s ability to hear sounds at different pitches and volumes.

How It Works: The patient wears headphones and listens to a series of tones at various frequencies and volumes, signaling to the hearing specialist when they hear a sound.

Purpose: Pure-tone audiometry identifies the type (sensorineural, conductive, or mixed) and severity of hearing loss.

  1. Speech Audiometry
    This test evaluates a person’s ability to hear and understand speech in different conditions.

How It Works: The patient listens to a series of spoken words at various volumes and repeats them back.

Purpose: Speech audiometry measures speech recognition ability and determines the potential benefits of hearing aids.

  1. Tympanometry
    Tympanometry assesses the function of the middle ear, including the eardrum and ossicles (tiny ear bones).

How It Works: A small probe is placed in the ear canal, and air pressure changes are applied to measure the eardrum’s response.

Purpose: This test diagnoses issues like fluid buildup, eardrum perforations, and Eustachian tube dysfunction.

  1. Otoacoustic Emissions (OAE)
    OAE tests measure sounds produced by the inner ear (cochlea) in response to auditory stimuli.

How It Works: A small probe emits sounds into the ear canal and records the cochlea’s responses.

Purpose: This test detects cochlear damage and is often used for newborn hearing screenings.

  1. Auditory Brainstem Response (ABR)
    ABR testing evaluates how well sound signals travel from the ear to the brain.

How It Works: Electrodes are placed on the scalp and earlobes to record the brain’s response to sounds delivered through headphones.

Purpose: ABR is used for individuals unable to participate in standard hearing tests, such as infants, and helps diagnose auditory nerve or brainstem disorders.

  1. Bone Conduction Testing
    This test examines how well sound travels through the skull bones to reach the inner ear, bypassing the outer and middle ear.

How It Works: A vibrating device is placed on the forehead or behind the ear to directly stimulate the inner ear.

Purpose: Bone conduction testing distinguishes between conductive and sensorineural hearing loss.

  1. Tuning Fork Tests
    These simple tests use a metal tuning fork to help diagnose the type of hearing loss.

How It Works: The vibrating tuning fork is placed on the skull or near the ear, and the patient reports what they hear.

Purpose: Tuning fork tests help differentiate between conductive and sensorineural hearing loss.

  1. High-Frequency Audiometry
    This test evaluates high-frequency sounds, which are often the first to be affected by hearing loss.

How It Works: Similar to pure-tone audiometry, high-frequency sounds are played, and the patient signals when they hear them.

Purpose: High-frequency audiometry is essential for detecting early-stage noise-induced or age-related hearing loss.

 

Understanding Hearing Test Results

After the tests are complete, the results are displayed on an audiogram, a graph that shows your hearing ability across different frequencies and volumes. Here’s how to interpret key components of an audiogram:

  • Hearing Thresholds: Measured in decibels (dB), these indicate the softest sounds you can hear. Normal hearing typically ranges between 0 and 25 dB.
  • Frequency: Measured in Hertz (Hz), frequency refers to the pitch of a sound. The audiogram shows frequencies from low (125 Hz) to high (8000 Hz).
  • Types of Hearing Loss:
    • Conductive Hearing Loss: Normal bone conduction thresholds with reduced air conduction thresholds.
    • Sensorineural Hearing Loss: Both air and bone conduction thresholds are reduced.
    • Mixed Hearing Loss: A combination of conductive and sensorineural loss.
  • Speech Discrimination Scores: This measures your ability to understand speech and is crucial for evaluating the effectiveness of hearing aids.

 

Why Regular Hearing Tests Matter

Regular hearing exams are essential for maintaining your auditory health. They allow for early detection of potential issues, which can significantly improve treatment outcomes. By identifying the type and extent of hearing loss, hearing specialists can create a customized care plan tailored to your needs.
