noise-shaped signal
1Noise shaping — is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit depth reduction of a digital signal. Its purpose is to increase the apparent signal… …
2Noise-induced hearing loss — (NIHL) is an increasingly prevalent disorder that results from exposure to high intensity sound, especially over a long period of time. Contents 1 Description 2 Mechanism 3 Types 3.1 …
3Time Reversal Signal Processing — is a technique for focusing waves. A Time Reversal Mirror (TRM) is a device that can focus waves using the time reversal method. TRMs are also known as time reversal mirror arrays, as they are usually arrays of transducers, but they do not have… …
4Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… …
5Crystal oscillator — A miniature 4 MHz quartz crystal enclosed in a hermetically sealed HC 49/US package, used as the resonator in a crystal oscillator. A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal …

7Stethoscope — Modern stethoscope. The stethoscope (from Greek στηθοσκόπιο, from στήθος, stéthos chest and σκοπή, skopé examination) is an acoustic medical device for auscultation, or listening to the internal sounds of an animal body. It is often used to… …
8Sound synthesis — Basics of sound When any mechanical collision occurs, such as a fork being dropped, sound is produced. The energy from the collision is transferred through the air and other mediums, and if heard, into your ears. On a small scale, the collision… …
