Hemi directional speakers provide solution for Turkish railway manufacturer
Sivas, Turkey
It is a full audio over IP system. The three existing Praesideo systems installed in separate locations in the factory work together; both audio and contact information are distributed over the IP network. The factory’s existing fiber-optic network configuration allowed optimal freedom in system design. It permitted the public address and voice evacuation equipment such as amplifiers, network controller, call stations and multi-channel interfaces to be located wherever required without having to install lots of additional cabling.
Bosch’s Hemi-directional Loudspeaker has an innovative acoustic design that uses 14 specially positioned speaker drivers combined with advanced filtering to eliminate any flat spots in the frequency response. This gives consistent, high-quality sound reproduction over the whole coverage area and a broad frequency response over the audio range from around 60 Hz to over 17 kHz.
“The TÜDEMSAS factory is a very demanding environment,” says Serhat Kacar, Project Manager, Entegre Electronics. “It’s noisy, with average ambient noise levels around 85 dB, so Bosch’s powerful Hemi-directional Loudspeakers are ideal. It’s also a dirty, dusty and hot environment, so the ruggedness of these speakers is vital. The units are suspended from the 15-meter high ceilings with steel wires.”
TÜDEMSAS are planning to install Bosch’s Hemi-directional Loudspeakers in two other factories in 2011.
