In this section you will find links to the videos we have published. The focus is on acoustic measurement technology, from room acoustics, building acoustics, and psychoacoustics to sound level measurements and, in particular, tutorials for our Akulap software.
On our website you will find a wealth of information to read up on, and the videos complement many topics.

Akulap mobile series
New tutorials for our new acoustic measurement app will be available here soon.
EDU-Entertainment Series
For many years, we have compiled a wealth of information on acoustic measurement technology on our website. We will also present some topics in a visually appealing way as videos.
- Part 1 A/C Weighting
- Part 2 Fast Slow Time domain Weighting
- Part 3: Total Harmonic Distortion (THD) demonstrated. A clear listening test. Our APX555 in the lab goes down to 0.0001%. Can you hear that?
- Part 4: Measure room/building acoustics with chirp/log sine. What is the magic behind it? How can we measure large rooms with tiny loudspeakers?
STI STIPA DIN60268-16 series Speech intelligibility
- STIPA ED5 test signal
- Part 1: Motivation, without going into the technology; that comes in Part 2. Here I explain why STI is a very powerful tool for optimizing room acoustics.
- Part 2: Fundamentals of STIPA measurement. What influences speech intelligibility?
This series will continue. Devices, practical measurements, the indirect method, etc.
Room Acoustics Series
Tutorials for Akulap
- Measuring sound levels with Akulap
- Measurement of reverberation time using the Chirp method
- Calibration of Akulap with a sound level calibrator
- Analysis of audio recordings with Akulap, here from an NTI XL2. Akulap can load the calibration information from the NTI XL2.

Measuring microphones
- Ultra-low noise: Comparison of different measurement microphones, from low-cost to high-end.
- Rode NT1 as an extremely low-noise measurement microphone?
- Measuring sound when it gets really loud >130dB
