The artificial head HMS IV.0 is probably the world’s best-known binaural recording system for aurally accurate recordings. Thanks to its 24-bit signal processing technology, the dynamic range of the HMS IV.0 is comparable to that of human hearing. Immediately after turning it on, the HMS IV.0 is ready for use.

Via the integrated headphone output, the recordings can be played back immediately after saving with aurally accurate equalization. This allows sound events to be recorded and played back just as a person would hear them if the person had been in the same position as the artificial head during the recording. The HMS IV.0 digital artificial head measurement system can be used as a binaural sensor in multi-channel applications. In addition, it can be connected directly to the measurement computer via USB for recording. Thanks to the internal memory, the artificial head can also be used as a completely independent stand-alone system.

For wireless control from a smartphone or tablet, a Bluetooth® adapter and the Android app HEAD Remote Control are available. Thanks to its battery, the HMS IV.0 can be used mobile and flexibly for several hours.
