The EARS module is a post-processing tool that adds the ability to perform auralizations of a room, allowing you to hear how it will sound with the best approximation available in the market. The module uses responses computed either with EASE® Standard or EASE Standard including the AURA module.
EARS gives you the possibility to generate a binaural transfer function based on the human head and the impulse response you have calculated for your room. You can then listen to music or any other stereo sound file or you could even use a microphone and produce your own signals live and with unlimited length. If you calculate several responses, you could even change your position in the room and compare different seats for example.
EARS is helpful:
- To obtain a good impression of the room’s acoustic signature.
- When one is not only interested in evaluating the room acoustics objectively - through the investigation of acoustic parameters - but also subjectively - by critically listening to the room’s acoustical behavior.
- In presentations to clients, to reinforce the acoustical problems of the room and potential solutions for them.
Both EASE Standard and EASE JR have an auralization feature already built-in, however they are limited to direct sound in EASE JR and full length results based on the added “statistical tail” in EASE Standard.
Although the EARS module can be used with the EASE Standard version, AFMG typically recommends using EARS along with EASE Standard including the AURA module, so more accurate, complete room impulse responses can be obtained in a considerably faster way.
- Expands EASE by the functionality of monaural and binaural auralization (in stereo) under consideration of the human head transfer function
- Auralization in realtime for audio samples of unlimited length as well as for live audio using suitable hardware
- Offline calculation of auralizations for export and unlimited replay on other hardware
- Possibility to mix different sources for auralization e.g. to simulate effects of masking noises
- Generate different noise signals for these purposes
- Stereo convolver for binaural auralization of stereo PA setups and the like
