The highest note of human speech is a soprano singer’s C7 (around 2048Hz) and the lowest note is the C2 of a bass singer (around 64Hz). Though we can’t scream much above 3000Hz, US singer Tim Storms has sung a note at 0.189Hz. Ironically, no human will ever hear it, although it is possible to feel it.

Max decibels for human ear

The counsel for accreditation in occupational hearing conservation (CAOHC) has stricter guidelines. “Under the stricter guidelines, workers may not be exposed to 85 decibels for more than 8 hours a day without hearing protection.

The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

For lower or higher frequencies, the dynamic is narrowed. However, as shown on this graph, all sounds above 90 dB are damaging the inner ear and even doing irreversible damage above 120 dB. (see " Noise: watch out ! If a sound level of 85 decibels is endured for eight hours, permanent damage can result. At 100 decibels, permanent damage can result after as little as 15 minutes. Above 120 decibels, the damage can be both permanent and immediate. Noise-induced hearing loss afflicts roughly 10 million Americans.
