Standard sound source-CRYSOUND

Standard sound source

The 604/611 standard sound source launched by our company can simulate the far-field sound source of the human mouth, which is suitable for testing the acoustic parameter indicators of the microphone test with a distance of 10cm-20cm. The frequency response (FR) curve 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.

CRY604 Loudspeaker

CRY604 standard sound source is a closed far-field sound source, which can effectively avoid problems such as short circuit and interference compared to conventional open sound sources. CRY604 standard sound source is suitable for acoustic test scenarios that require a single sound source within the long-range (30 cm - 100 cm) free field. The frequency response characteristics comply with the international standard IEEE 269.661 and such characteristics as good low and high frequencies are also available.
CRY611 Loudspeaker

CRY611 standard far field speaker with built-in high performance speaker can produce high frequency wide and low distortion sound.Compact volume is convenient for small space such as silencer box to use;Mounting holes are reserved at the top and bottom of the box body for flexible installation in required positions;The circular box can effectively avoid the influence caused by sound reflection.Especially suitable for remote sound source scenarios such as smart speaker, omnidirectional conference terminal mike, smart home equipment and smart TV.
