The acoustic heads of the sensors are shaped and designed taking into account the anatomical characteristics of the area being investigated.

Acoustic transducers, such as microphones, can be located in the vicinity of sprinkler heads.

A positioning system is configured to position the acoustic printheads with respect to the substrate.

The acoustic heads of the sensors are shaped and designed taking into account the anatomical characteristics of the area being investigated.

An array of stationary ultrasonic acoustic transducers (30) are arrayed within the walls of the tub which are connected to movable ultrasound heads (30).

An acoustic wave detector (24) detects acoustic waves.

The CHT-02D torpedo manufactured by North Korea utilizes acoustic/wake homing and passive acoustic tracking methods.

The devices (10) may be used along with new head mounted acoustic technologies for improved voice communication systems in inherently noisy environments.

The invention relates to an arrangement for generating sound waves or anti-sound waves.

The downgoing acoustic wavefield is removed from the total acoustic wavefield.

In this manner synthesized acoustic data can be generated which after conversion into acoustic signals do not differ from the corresponding naturally produced acoustic signals.

Acoustic detectors on the logging tool measure the generated acoustic waves.

The marine seismic data has a total acoustic wavefield that includes an upgoing acoustic wavefield and a downgoing acoustic wavefield.

Acoustical panels and methods of making acoustical panels are provided.

Are acoustic foams acoustic absorbers or acoustic insulators?
