The CRY605 is a mouth simulator is suitable for the test of the acoustic parameters testing of telephones, headsets, in-ear devices with microphones, smart speakers, TV´s – any device with microphones used in voice communication. The frequency response and other properties comply with the requirements of IEEE 269, 661 and the requirement for “mouth reference point” for transmitting acoustic signals in ITU-T P51. It is a standard sound source for acoustic measurement acoustic measurement.
