In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
In early 2015, most or all of Polk's non-technical jobs were moved from the Baltimore office to the headquarters of the parent company, Sound United, in Carlsbad, California. At that time, Polk's engineers joined with those of Definitive Technology, and the Audio and Acoustics Research and Development [ARAD] center was established in Owings Mills.
This list of car audio manufacturers and brands comprises brand labels and manufacturers of both original equipment manufacturer (OEM) and after-market products generally related to in-car entertainment that already have articles within Wikipedia. While components sold by these companies have much in common with other audio applications or may ...
Active noise cancelling (ANC) is a software process that uses existing in-vehicle infotainment hardware to eliminate undesirable noise within the interior of a vehicle. This elimination technique is known as harmonic order reduction, where unwanted audio signals are identified by sensors and filtered out of the overall interior vehicle sound. [3]
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Each shift in offset voltage or current often lasts from several milliseconds to seconds, and sounds like popcorn popping if hooked up to an audio speaker. [2] Burst noise was first observed in early point contact diodes, then re-discovered during the commercialization of one of the first semiconductor op-amps; the 709. [3]
Some models of the BMW M5 add noise to the car's audio system, for instance, [1] and the 2015 Ford Mustang also added a system for sending the car's engine noise through its speakers. [4] Multiple manufacturers have shaped the engine compartment or installed resonant pipes within it in order to direct greater amounts of actual engine noise to ...
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
