Acoustic – G 10, the highest pitch sung by Georgia Brown, who has a vocal range of 8 octaves. ^ "Black Hole Sound Waves – NASA Science". ^ 20 Hz is considered the normal low frequency limit of human hearing.

2024年11月4日 · The popular sampling rate for speech is 8 kHz—below audio CD quality at 44.1 kHz. This is because the human voice has a frequency range of approximately 0.3 to 3 kHz. With this example in mind, a higher kHz doesn't always mean better quality audio.

2021年12月4日 · If you look at digital sound equipment, you can see that in most hardware the minimum recording value is 8 kHz or 8,000 samples per second. So if you look at a fresnel lens you could run your finger across it and make a scratching sound.

For humans, normal hearing is between −10 dB (HL) and 15 dB (HL), [2][3] although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing. Hearing thresholds of humans and other mammals can be found with behavioural hearing tests or …

Humans hear frequencies from 20 Hz up to 20,000 Hz. As we get older, or exposed to loud sounds which damage our ears (such as loud concerts), the upper limit decreases. This test helps you benchmark the highest boundary of your system's frequency extension.

Audio bandpass was increased to 20 KHZ or better with FM because the higher carrier frequencies could handle higher bandwidth for better music reproduction. Stack up some xylophones or bells or other high pitched instruments and they can get enough harmonic energy into the higher frequencies.
