To go from A 4 up two semitones (one whole tone) to B 4, multiply 440 twice by the twelfth root of two (or once by the sixth root of two, approximately 1.122462). To go from A 4 up three semitones to C 5 (a minor third ), multiply 440 Hz three times by the twelfth root of two (or once by the fourth root of two, approximately 1.189207).
Bats that can detect 200 kHz cannot hear very well below 10 kHz. [25] In any case, the most sensitive range of bat hearing is narrower: about 15 kHz to 90 kHz. [25] Bats navigate around objects and locate their prey using echolocation. A bat will produce a very loud, short sound and assess the echo when it bounces back.
On some keyboards—a good example of such an instrument being Yamaha's programmable synthesiser-workstation, the Yamaha EX5 [1] [2] [3] —the player can select the effects to which aftertouch applies. This allows a performer to custom-tailor the effect that they desire. It may also facilitate the imitation of various non-keyboard instruments.

The smallest signal without dithering is 1, so the number of different levels is one less, 2 16 − 1. So for a 16-bit digital system, the Dynamic Range is 20·log(2 16 − 1) ≈ 96 dB. Sample accuracy/synchronisation Not as much a specification as an ability.
The horizontal axis shows frequency in Hertz. In acoustics, loudness is the subjective perception of sound pressure.More formally, it is defined as the "attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud". [1]
[2] [3] [4] In air at atmospheric pressure, these represent sound waves with wavelengths of 17 metres (56 ft) to 1.7 centimetres (0.67 in). Frequencies below 20 Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. Sound frequencies above 20 kHz are called ultrasonic.
