Question: what hz should i be able to hear?
Answer: The 'normal' hearing frequency range is is about 20 to 20,000Hz for a healthy young person . 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. ... So by the time we hit middle-age, we can expect to hear up to around 14,000Hz.
