Akulap the measurment system for room and building acoustics and noise measurments (Code: )

Ask a question

AkuLap is a powerful tool for measuring acoustical parameters with a PC. By using the PC environment, it is not only a cost efficient replacement for classical laboratory equipment. AkuLap offers more powerful features combined with a comfortable user interface. Typical applications are in the area of audio-measurements with focus to room acoustics, building acoustics and noise measurement. AkuLap uses highly sophisticated techniques like „Maximum Lenght Sequences“ MLS or LOG-sweep (Chirp) to measure reverberation parameters fast and reliable.
By using small notebooks or tablet PCs , you can easily build a mobile measurement system.

We offer different measurement interfaces. It start from compact USB interfaces to high end capsules from major brands e.g. Bruel&Kjaer, GRAS, PCB etc


This article is just a basic description, you can't buy it in the shop. Instead you can buy Akulap base package and other plug-ins in our web shop.
