Comment Bei der Übertragung von Luftschall über ein Bauteil, z. B. über die Wand einer Maschinenkapsel, über eine Gebäudewand oder eine Gebäudedecke, durchdringt nur ein Bruchteil der auffallenden Schallenergie das trennende Bauteil, und zwar infolge der teilweisen Reflexion an der Bauteiloberfläche, der Umwandlung in Wärme (Dissipation) und der Ableitung als Körperschall in benachbarte Bauteile. Damit wird von dem Bauteil weniger Schall abgestrahlt, als auf der anderen Seite auffallt. Dieser Effekt wird als Schalldämmung bezeichnet. Die Schalldämmwirkung eines Bauteiles wird durch das Verhältnis der auf einer Seite dieses Bauteiles auffallenden Schalleistung zu der auf der anderen Seite abgestrahlten Schalleistung gekennzeichnet.

Definition instrument used as an accurate and stable reference source for calibrating a sound level meter before use Reference "COM-EN, based on: Brown, M.V. ""The Medical Equipment Dictionary"". Chapman and Hall Ltd. London 1986. http://home.btconnect.com/MalcolmBrown/entries/PISTONPHONE.html [23.5.2013]"
Comment The device is normally battery powered and comprises a small electric motor which drives a piston situated at one end of a small (a few millilitres) cavity into which the microphone of the sound level meter is introduced. The known and accurate excursion of the piston allows a high and constant sound pressure level to be achieved. A similar device, known as a sound level calibrator, is used for the same purpose but comprises an audio oscillator (1 kHz) and a small loudspeaker rather than a motor and piston. In addition to calibrating sound level meters they are also required for the calibration of a hearing aid test box and they are commonly found in audiology or medical physics departments.
Comment Il se présente généralement sous la forme d'une cavité dans laquelle on introduit le microphone à étalonner (le diamètre de la cavité et celui du microphone doivent correspondre). Le pistonphone émet un signal sonore à une fréquence fixe, qui va induire une pression vibratoire au niveau du microphone donnée par le constructeur du pistonphone. Les pistonphones les plus utilisés fonctionnent autour des 250 Hz et induisent une pression de l'ordre de 100 dBa.

Comment It is a type of add-in card. Some systems have the module as part of their original design. The sound card takes digitized audio signals from the processor and converts them into an analog audio signal used to drive headphones or as input to an audio amplifier or active speakers.

Comment "A ratio higher than 1:1 indicates more signal than noise. While SNR is commonly quoted for electrical signals, it can be applied to any form of signal (such as isotope levels in an ice core or biochemical signaling between cells).In less technical terms, signal-to-noise ratio compares the level of a desired signal (such as music) to the level of background noise. The higher the ratio, the less obtrusive the background noise is.""Signal-to-noise ratio"" is sometimes used informally to refer to the ratio of useful information to false or irrelevant data in a conversation or exchange. For example, in online discussion forums and other online communities, off-topic posts and spam are regarded as ""noise"" that interferes with the ""signal"" of appropriate discussion.See also: Wikipedia > Signal-to-noise ratio, Improving SNR in practice, http://en.wikipedia.org/wiki/Signal-to-noise_ratio#Improving_SNR_in_practice, http://en.wikipedia.org/wiki/Signal-to-noise_ratio#Improving_SNR_in_practice [7.1.2011]"
