Are Audiograms accurate?
How accurate is an audiogram? Because an audiogram covers a full range of frequencies it has the potential to be highly accurate. Handheld audiometers of this kind have a sensitivity of 92% and a specificity of 94% when it comes to detecting sensorineural hearing impairment.
How often should Audiograms be taken?
Employers must provide annual audiograms within 1 year of the baseline. It is important to test workers’ hearing annually to identify deterioration in their hearing ability as early as possible. This enables employers to initiate protective followup measures before hearing loss progresses.
What does dB HL mean on a hearing test?

The decibel ( dB) is a logarithmic unit of measurement used to express the magnitude of a sound relative to some reference level. Decibels in hearing level, or dB HL, is com- monly used in audiology because it refers to the decibel level on the audiometer.
How do I convert SPL to HL?
To convert SPL readings to HL readings, audiometers are calibrated to add a specific amount to each frequency tested. This amount varies by frequency. For example, at 125 Hz, it adds 45 dB, while at 1,000 Hz it only adds 7 dB. Likewise, at 4,000 Hz it adds in 9.5 dB, while at 8,000 Hz it adds in 13 dB.
How do ENT check for hearing loss?
The ENT Doctor leads a two-phase test: otoscopy, a complete visual clinical examination of the eardrum and duct, and audiometry, to measure your hearing. If a hearing aid is necessary, the ENT doctor will then prescribe a hearing test with a hearing care professional.
How do audiologists test for hearing loss?
An audiometry test is when the audiologist uses different sounds to check how well you can hear. You will usually wear headphones, earphones or sometimes bone-conduction headband.
