The signals are processed to cancel the noise from the desired signal, producing improved voice sound quality. In some cases, noise can be controlled by employing active vibration control. This approach is appropriate when the vibration of a structure produces unwanted noise by coupling the vibration into the surrounding air or water.
Initially, the audio quality was mediocre and a step forward was the invention of high fidelity headphones. [3] [4] Headphones exhibit a range of different audio reproduction quality capabilities. Headsets designed for telephone use typically cannot reproduce sound with the high fidelity of expensive units designed for music listening by ...
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...
Without power, some models do not function as regular headphones. Any battery and additional electronics may increase the size and weight of the headphones compared to regular headphones. The noise-cancelling circuitry may reduce audio quality and add high-frequency hiss, although reducing the noise may result in higher perceived audio quality ...
The audiophile seeks to achieve high sound quality in the audio reproduction of recorded music, typically in a quiet listening space in a room with good acoustics. [ 2 ] [ 3 ] Audiophile values may be applied at all stages of music reproduction—the initial audio recording , the production process, the storage of sound data, and the playback ...
Introduced in 2006, [1] DSEE is included in Sony's digital Walkman products and freeware SonicStage CP (version 4.2 or higher), x-app, and Music Center for PC.In operation, it analyzes irreversibly compressed music files such as MP3, ATRAC3, AAC, and WMA, and performs predictive calculations to compensate for high-frequency sounds lost due to compression, thereby improving sound quality.

Diaphragms are also found in headphones. Quality midrange and bass drivers are usually made from paper, paper composites and laminates, plastic materials such as polypropylene, or mineral/fiber-filled polypropylene. Such materials have very high strength/weight ratios (paper being even higher than metals) and tend to be relatively immune from ...
