ACQUA provides more than a measurement! In addition to archiving single number values such as loudness ratings or distortion and measured data such as frequency response, ACQUA can also archive the digital recording of the measured signal. By setting up play lists, the user can perform subjective evaluations of different test objects, different operating conditions, etc. Interactive IIR and FIR filters allow the user to alter the response of a test object. Filter a test signal using a telephone's frequency response in order to simulate the telephone on a network connection and hear the result. Edit a test signal by mixing unsteady background noise and speech in order to measure system response due to comfort noise injection. For automating the set-up delivery and collection and analysis of results, HEAD acoustics has developed the SQuare Listening Jury Test System.
Jury Testing and dedicated Listening Rooms are key elements in any program to improve product speech quality.
It is important to gain an understanding of a product's sound from the customer's perspective. Jury tests involve gathering groups of people who represent the targeted customer group and presenting them with various product sound files with the objective of determining sound preferences, typically Mean Opinion Score (MOS) for different design configurations, competitive products, and even simulated systems.
Descriptive listening tests are also important for making design decisions, establishing benchmarks and targets, and validating improvements. Descriptive testing involves the use of expert listeners, typically development engineers and other design team members, to accurately identify and rate all the attributes present in a sound file. Results from descriptive testing are used for design discussions and to help guide engineers in choosing analyses (ACQUA) that best correlate with product sound attributes.

Listening Room Set-up
A properly set up Listening Room greatly enhances the realism and accuracy of the playback of product sounds. HEAD acoustics offers the HEADphone Playback Systems as the standard method for playing back recordings made with a Head and Torso Simulator. Another option, especially for larger groups or for groups that do not want to be encumbered with headphones is speaker-only playback. HEAD acoustics offers specially developed speaker and headphone playback systems that all can be controlled automatically with the SQuare software. Furthermore, HEAD acoustics provides services to equalize and calibrate your room to ensure the highest level of playback accuracy.
