Audiometers

An audiometer is used to evaluate a person's hearing ability. It measures the range and sensitivity of a person’s hearing across different frequencies and intensities, helping to diagnose hearing loss or auditory disorders.

The main parts of an audiometer include:

• Headphones or Earphones: For delivering sounds to the patient.
• Test Tones Generator: Produces various frequencies and intensities of sound.
• Transducers: Convert electrical signals into sound.
• Response Button: Used by the patient to indicate when a sound is heard.
• Display/Interface: The audiologist can control the device and view results.

Audiometry tests are needed by individuals who show signs of hearing loss, have difficulty understanding speech, have been exposed to loud noises for prolonged periods, or have a medical history that suggests a risk of hearing impairment.

Audiometers typically have one or two channels. Dual-channel audiometers allow for more complex testing and can simultaneously present different signals to each ear.

The two main types of audiometry are:

• Pure Tone Audiometry: Measures hearing sensitivity for various tones and pitches.
• Speech Audiometry: Assesses understanding and clarity of speech at different volumes.

Audiometers are classified into:

• Screening Audiometers: Used for basic hearing screening; simple functionality.
• Diagnostic Audiometers: Offer comprehensive hearing assessment; more features and test options.
• Clinical Audiometers: Used in advanced clinical settings; equipped with specialised testing capabilities.

The audiometer delivers sounds at various frequencies and volumes through headphones or earbuds to the patient, who responds to each sound. The responses are recorded, creating an audiogram representing the patient's hearing capabilities.

While screening audiometers can indicate potential hearing issues, they cannot diagnose the type or severity of hearing loss. A diagnostic audiometer is required for a detailed evaluation.

Portable audiometers may have fewer features and less precision than full-sized, clinic-based audiometers, but they are invaluable for initial screenings and reaching populations not easily accessible to traditional healthcare facilities.

Yes, portable audiometers are designed to be accurate for screening and preliminary assessments. However, results from portable audiometers should be followed up with comprehensive clinical testing if a hearing issue is detected.
