A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.
RFID (Optional) location on a Latitude E6410 Dell used the "E-series" name up through the 2016 models, and new 2017 models drop the "E." [ 8 ] [ 9 ] and Dell E-Port Replicator with it. Latitude computers are available in four series: the 3000, 5000, 7000, and 9000.
Latitude ON is an instant-on computer system made by Dell. It is a combination of software and hardware [ 1 ] developed by Dell and used in some of their Latitude laptops. [ 2 ] The system is based on a dedicated ARM processor ( Texas Instruments OMAP 3430) that runs a custom version of a Linux OS.
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone , it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the ...
The output of the generator is fed to a transducer in a half-inch cavity into which the sound level meter microphone is inserted. The sound level generated is 94 dB, which corresponds to a root-mean-square sound pressure of 1 pascal and is at a frequency of 1 kHz where all the frequency weightings have the same sensitivity. For a complete sound ...
A Dell Latitude E4310 laptop with a pointing stick (upper middle) and a touchpad (bottom). They were commonly featured together on Dell Latitude laptops, beginning in the late 1990s. The pointing stick can be used in ultra-compact netbooks [13] where there would be no place for a touchpad.
A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones , hearing aids , public address systems for concert halls and public events, motion picture production, live and recorded audio engineering , sound ...
The predecessor of the directional boundary microphone was a directional microphone placed in an Electrovoice Mic Mouse, a foam block that suspended a conventional microphone horizontally just above a surface. Because conventional microphone diaphragms are relatively large (> 1 cm diameter), phase interference from surface sound reflections ...
