Audible warning means a warning by sound signal.

Audible warning means a warning by sound signal.

The multimedia processor, in response to an instruction, compresses the sound signal into a sound file or decompresses the sound file into the sound signal.

A user may control the amount of surround sound effect that is combined with stereo sound effect, and the amount of stereo sound effect that is combined with monophonic sound effect.

Thereafter a sound pattern comparison unit compares the recorded sound pattern with a predefined sound pattern.

In a preferred composite material, three base layers are provided to impart sound deadening, sound dispersion, sound absorption, and sound durability.

The system compares the sound level data with a sound threshold and generates an alarm signal when the sound level data exceeds the sound threshold.

A front sound passage communicates between the front sound inlet and the front chamber, and a rear sound passage communicates between the rear sound inlet and the rear chamber.

A sound system and method for modeling a sound field generated by a sound source and creating a sound event based on the modeled sound field is disclosed.

The third sound transducer (105) is positioned between the first sound transducer (101) and the second sound transducer (103).

The sonic receiver (11) may be excited by sonic energy, which causes the sonic receiver (11) to itself introduce sonic energy into the cartridge (10).

The alarm may be visual, audible or both.

A sonic field is measured by a plurality of sensors (20;220), said field consisting of a primary sonic field and a superposed secondary sonic field for the reduction of sound.

The invention relates to a method for active reduction of sound emissions from drive mechanisms.
