“Perfect” hearing is having a “0 dB” score at all frequencies. Anything below 20 dB is significantly worse than normal. A 100 dB loss at all frequencies means you hear nothing. Hearing loss is also divided up by the timing.

What are sounds above 20000 Hz called?

The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. Frequencies above 20,000 Hz are known as ultrasound.

What does SRT mean on a hearing test?

speech reception threshold (SRT) | Audiology.

Does everyone get hearing loss?

Having trouble hearing can make it hard to understand and follow a doctor’s advice, respond to warnings, and hear phones, doorbells, and smoke alarms.

What does a normal hearing test look like?

If you have a standard audiogram, highlight the 20 dB line that crosses the graph from left to right. If all of the X’s (for the left ear) and all of the 0’s (for the right ear) fall above the line you just drew, you have normal hearing. If anything is below that 20 dB line, you have a hearing loss.

What is the normal range of hearing?

about 20 to 20,000HzThe ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it’s the upper frequencies we lose first.
