The sensitivity of the human ear ranges from 20 Hz to 20 kHz. Under ideal conditions in a laboratory, humans have detected sounds as low as 12 Hz.
An adult can hear up to 10 kHz, but it depends always on the level this frequency has. The sensitivity of hearing goes slowly down with age. If there is no level given in the question. the answer is really useless.
Audible sounds - are those that fall within the scope of human hearing. These are sounds that are typically in the frequency range of 50 Hz to 20 kHz. Frequencies below 50 Hz are classed as ULF (ultra-low frequency) sounds. Those above 20kHz are labelled as ultrasonic sounds.
Depends on your ears. If you are young you will hear things up to around 15 kHz, say. But as you get older this falls, so some music you can't hear.
Sounds in this range are known as ultrasound. They have frequencies from about 20 kHz to a few GHz. Even the sounds at the low-frequency end are beyond the ability of most people to hear.

2 Hz to 20 KHz .
Domestic cats can hear sounds in the range of about 2 kHz to 65 kHz. The average hearing range for humans is about 02 kHz to 20 kHz. Therefore cats hear better than humans.
4000 Hz is wrong, since your hearing is very sensitive at a younger age. A averge 30-40 year old adult might be able to hear 5000Hz, but a teenager from 12-18 could most likely hear a 6000-6500Hz like nothing fazed them.
The sensitivity of the human ear ranges from 20 Hz to 20 kHz. Under ideal conditions in a laboratory, humans have detected sounds as low as 12 Hz.
Loud enough to be heard from around 2 miles away.
oh my god I'm talking about does it hurt a dogs ears when they hear ultrasound frequency.
BW = (1 MHz - 10 KHz) = (1,000 KHz - 10 KHz) = 990 KHz
Assuming that the receiver uses a high-side local oscillator and an IF of 455 KHz, the image frequency is 910 KHz above. When tuned to 1600 KHz, the image frequency would be 2,510 KHz.
Depending on age, humans can hear between 20 Hz and 15-20 kHz. Bat calls have a frequency range of 9 kHz to 200 kHz.So Yes.
If 10 V input causes a frequency shift of 4 kHZ then 2,5v causes a freuency shift of 1 kHz. The input signal frequency of 1 kHz is irelevant.
