Can you hear 400 Hz?

Can you hear 400 Hz?

Normal human hearing encompasses frequencies from 20 to 20,000 Hz, an impressive range. Sounds below 20 Hz are called infrasound, whereas those above 20,000 Hz are ultrasound. Dogs can hear sounds as high as 30,000 Hz, whereas bats and dolphins can hear up to 100,000-Hz sounds.

Which is louder 50 Hz or 1000 Hz?

The 1,000 Hz tone will seem far louder than the 50 Hz tone for most people, even though the sound levels are identical. Humans have far better hearing near 1000 Hz than at low frequencies like 50 Hz.

Can two cars share the same 27MHz frequency?

With selectable bands, you should be able to flip the car’s designated frequency from the default frequency to one of the alternate frequencies. As long as the two vehicles are operating on different channels on the 27MHz frequency range, they should not interfere with each other’s operation.

What is the sample rate of the tone generator?

You will hear a pure tone sine wave sampled at a rate of 44.1kHz. The tone will continue until the stop button is pushed. The tone generator can play four different waveforms: Sine, Square, Sawtooth and Triangle.

How do I change the radio frequency on my RC car?

This default radio channel should also be designated somewhere on the outside of the controller or in the RC manual. With most RC vehicles, the only viable option is to modify the frequency from 27MHz to 49MHz, and even this is not done easily. If you decide to open up your remote control to adjust the frequency, be very careful.
