Aspects and Properties of Transmitters, sound damper channels, walls, elastic bearings. All of these constructions transmit a time-dependent stimulus signal and in the process, change the signal. As transmitters are often referred to as ‘systems,’ this chapter could otherwise be titled ‘The Basics of System Theory’.

方便

Erfolgreiches Management als Hochbegabter, the sound travels a distance of nearly 700m and hits the room surfaces several times; the sound waves are reflected several times at the walls under different angles. Each reflection at a (rigid) plane surface can be regarded as coming from a sound source which is mirrored at the wall.

Fundamentals of room acoustics, the sound travels a distance of nearly 700m and hits the room surfaces several times; the sound waves are reflected several times at the walls under different angles. Each reflection at a (rigid) plane surface can be regarded as coming from a sound source which is mirrored at the wall.

Fundamentals of Active Noise Control,described in Chapter 11). The disruptive, somehow unavoidable sound source is referred to here as the ‘primary’ source; additional electro-acoustic converters which are intended for use as noise reducers are referred to as ‘secondary’ sources.
