Features

This database has been developed for evaluation on the performance of telephone sets, public address systems, and speech input terminals with significant ambient noise.

The database is recorded on CD-ROM disks.
The signals in the data area can be read by a PC.
The noise recordings were performed using 4 separate microphones and 4 digital channel recorders then the database is converted into monaural sound for the ease of mixing with your sound files.
These CD-ROMs provide better sensation of reality than conventional commercial CD titles for sound effects.
