Noise exposure measurements are often expressed as dB(A), a scale weighted toward sounds at higher frequencies, to which the human ear is more sensitive. If available, office tympanometry can also help detect conductive hearing problems. Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. It's important to address high-frequency hearing loss as its effects extend far beyond struggling to hear. Noise-induced hearing loss therefore represents excessive wear and tear on the delicate inner ear structures.
