Product Overview

ACQUA includes a multi-channel analysis system for diagnosis of acoustic and/or electric transmission paths up to 192 kHz. With the measurement and analysis software, users can gather and evaluate measurement data in a simple and quick manner via measurement descriptors (SMD; Single Measurement Descriptor). These SMDs are pre-defined, adaptable and embedded in the database structure. All telecommunication-specific tests comply with international standards (for example ETSI, ITU, 3GPP, GCF, PTCRB, GSMA).


Thus, ACQUA is the reliable basis for the complete measurement chain: From the generation of complex excitation signals through the automated conduct of measurements and the analysis of measurement signals to secure storage and documentation.



  • Measurement and analysis software for automated testing voice quality and audio quality of different devices
  • Powerful data acquisition and analysis system for electroacoustic tests with sampling rates up to 192 kHz
  • Numerous important international standards in audio and telecommunications are implemented as editable data bases for the use in ACQUA (ACQUA standards)
  • Standards developed by HEAD acoustics (HEAD acoustics Quality Standards) are available for a wide range of applications

Product Features

  • In ACQUA, test procedures and hardware equipment are configured and controlled database-driven
  • The software contains pre-defined measurements for fast, automated and guided electroacoustic tests according to various international standards
  • The user-friendly “Quick Start” menu provides quick access to favorite projects and to a dynamic list of recent projects and test objects
  • ACQUA offers outstanding possibilities for signal preparation and manipulation
  • The software allows analysis in the time and frequency domain
  • A variety of perceptively motivated quality measures is available
  • The analysis software enables electroacoustic tests for improving voice quality and audio quality with any test signals: real speech, sine, sine stepped sweep, multi-sine, pseudo noise, artificial voice (P.50), pink noise, white noise, Hoth noise, test signals according to ITU-T recommendation P.501 (e.g. composite source signal)
  • ACQUA stands out through comfortable and useful report and documentation functions (e.g. A/B comparison of multiple measurement objects, benchmarking, Quality Pie reports)
  • ACQUA provides possibility to build custom standards and measurement sequences
  • The "Workplace Settings" allow easy and intuitive management and configuration of all hardware components in the lab
  • The complete measurement chain is clearly arranged in ACQUA – from connection of the analysis software over labCORE to the artificial head measurement system, third party equipment, and the device under test
  • The measurement and analysis software can be extended with a wide variety of software options (ACOPTs) and can thus be individually adapted to specific fields of application

Product Applications

  • Electroacoustic tests to optimize voice quality and audio quality (algorithms, devices and systems)
  • Conformance tests according to telecommunication standards
  • Research and development (R&D)
  • Quality control
