High Frequency Testing

Humans can hear a wide range of sound frequencies, but we cannot hear everything, especially sounds on the higher end of the frequency spectrum.Often clients with normal hearing tell us about their challenges in understanding speech in noisy environments. This is an essential communication skill that varies widely between individuals and is poorly understood. There are indicators that extended high-frequency (EHF) hearing, beyond the currently tested range of clinical audiometry, contributes to speech perception in noise.

Why should I get a High Frequency Hearing Test?

Hearing Loss is the most common neurodegenerative conditionand unaddressed hearing loss is estimated to pose an annual global cost of over US$750 billion. But EHF hearing difficulties are far more common and undiagnosed in otherwise normally hearing young adults and it predicts a self-reported difficulty in hearing speech in noise. Evidence suggests that EHF test is a missing link between audiometry and speech perception and may be a sensitive predictor of age-related hearing loss much earlier in life when preventive measures can be effectively deployed.

High frequency audiometry is also helpful when testing hearing issues caused by ototoxicity, noise exposure, and acoustic traumas or in the assessment of patients with tinnitus. The frequency area is more susceptible to the effects of external factors such as medication and loud noises relative to the low and mid frequencies.

What does High Frequency Test Include?

  • Includes regular test battery
  • Extra testing includes:
    • extended high frequency audiometry up to 16kHz, (frequencies above 8000Hz have a +-20 dB error, should be used to identify hidden hearing loss and evidence of speech in noise difficulties rather than severity),
    • uncomfortable loudness thresholds 500, 1000, 2000, 3000, 4000, and 8000Hz, few studies investigated extended high frequency LDLs, therefore, just a general guide as to whether individual is experience hyperacusis in relation to early noise induced hearing loss or other hearing abnormalities
    • speech in noise testing such as the LiSN test, SNR chart to determine severity of speech in noise processing difficulties (mild, moderate etc.)

How much time is required for the High Frequency Test?

High Frequency Testing takes about 60 minutes. Extra follow-up might be required for cases of significant hearing loss or diagnosis of related medical conditions.

Why is High Frequency Test essential to keep our community HearFit?

High Frequency Test may be used for populations consisting of audiophiles who wish to know their exact hearing levels, for monitoring purposes of ototoxicity or noise induced hearing loss, and those who specifically have complaints of hearing in noise rather than experiencing general hearing difficulties to lead to more specific hearing in noise recommendations like enhanced hearing devices, personal audio amplifiers, noise protectors. In short High Frequency Test can be an early predictor of future hearing challenges.
