1. What is Pure Tone Sensitivity?

Pure Tone Sensitivity refers to the threshold of hearing for pure tones, measured in decibels (dB). It represents the quietest sound a person can detect at various frequencies, providing crucial information about hearing ability.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Threshold dB \) — Hearing threshold in decibels

Explanation: The sensitivity is directly equal to the measured threshold value in decibels, with lower values indicating better hearing sensitivity.

3. Importance of Pure Tone Sensitivity

Details: Pure tone sensitivity measurements are fundamental in audiology for diagnosing hearing loss, determining hearing aid requirements, and monitoring hearing health over time.

4. Using the Calculator

Tips: Enter the threshold value in dB obtained from audiometric testing. The calculator will display the pure tone sensitivity value.

5. Frequently Asked Questions (FAQ)

Q1: What is considered normal hearing sensitivity?
A: Normal hearing sensitivity typically ranges from 0 to 20 dB across frequencies. Values above 20 dB may indicate some degree of hearing loss.

Q2: How is pure tone sensitivity measured?
A: It's measured using an audiometer that presents pure tones at various frequencies and intensities through headphones or bone conduction.

Q3: What factors can affect pure tone sensitivity?
A: Age, noise exposure, ear infections, genetic factors, and certain medications can all affect hearing sensitivity.

Q4: How often should hearing sensitivity be tested?
A: Adults should have baseline testing in their 20s and regular screenings every 3-5 years. More frequent testing is recommended for those with risk factors.

Q5: Can hearing sensitivity improve?
A: While some types of hearing loss are reversible, most sensorineural hearing loss is permanent. Early detection and intervention are crucial.
