Listening Bar: Unkompress, Berlin
Room Acoustics Measurement

Inspired by the Japanese culture of ‘ongaku kissa’, which focuses on conscious music consumption, listening bars based on this model are also increasingly emerging in Europe. One such example is the Berlin listening bar Unkompress, where I did a room acoustic measurement to analyse the existing acoustic situation.

Warm hi-fi system meets rotary mixer:

The Berlin listening bar Unkompress is a contemporary interpretation of Japanese ongaku kissa culture, which focuses on conscious music listening and combines it with a minimalist, high-quality catering concept. Against this backdrop, I carried out a room acoustics measurement that essentially combines the uses of music listening with the acoustically desirable conditions of a bar. In other words, this means finding an acoustic sweet spot that dampens the sound level from the catering operation while still giving the hi-fi system enough space to unfold its sound spatially.

The interaction between room geometry, acoustic equipment and the permanently installed hi-fi system with Klipsch Cornwall loudspeakers, a resør 3300 rotary mixer and Technics 1210 MK2 turntables was examined carefully. In consultation with the owner, Kevin, the measurement results were jointly evaluated and possible development steps discussed. It became clear that the Unkompress Listening Bar should be continuously refined acoustically in order to make the listening experience even more intimate and high-quality. It will be exciting to see how the room, sound and concept will be further refined in the future.

I personally recommend stopping by to listen calmly!

HiFi Living Environment
Room Acoustics Measurement & Consulting, Leipzig

Open living spaces with high-quality hi-fi systems set special demands on room acoustics. This project investigated how a powerful stereo setup, including a large subwoofer, can be acoustically integrated into a hybrid living environment – and why the low-frequency range in particular requires special attention.

Living spaces are increasingly being used for multiple purposes:

Listening to music, watching television, cooking and socialising often take place in an open-plan space. From an acoustic point of view, however, this creates complex interactions, as different room volumes, hard surfaces and noise sources form a common sound field. While high-quality loudspeakers often deliver impressive performance in the mid and high frequencies, the real challenges lie in the bass and sub-bass ranges. Powerful subwoofers with large membrane surfaces in particular bring enormous energy into the room, which without targeted control can quickly lead to booming, uneven bass distribution or disturbing structure-borne noise transmission.

A significant part of the acoustic work in this project consists of first ‘taming’ the low-frequency components of the frequency spectrum before fine-tuning the sound can take effect. This includes analysing the room acoustics and recommending mechanical and acoustic measures to prevent the room itself from becoming the dominant sound factor. Only when the low frequencies are under control can the precision of the KEF Blade loudspeakers, the dynamics of the McIntosh mono power amplifiers and the performance of the 18-inch subwoofer be fully exploited in this project.

The project exemplifies how important a holistic approach combining room acoustics and audio technology is in order to achieve both precise music reproduction and an acoustic environment suitable for everyday use in hybrid living situations.

Workshop: Your Room Sucks!
Trial & Error
DIY Music Conference

Why does your mix sound great in headphones but falls apart in your room? Why does the bass boom in one corner and vanishes in another? In this hands-on workshop, we dive into the world of acoustics – and show you what you can do about it, without breaking the bank. We will take a closer look at:

Acoustic Foundations
We’ll start with an accessible introduction to room acoustics, building acoustics, and psychoacoustics – theory with a direct connection to real-world applications.
Studio-Specific Challenges
What makes a room truly usable for production or critical listening? We’ll explore the unique acoustic demands of studio environments.
Live Room Measurement
We’ll perform a live acoustic measurement of the actual workshop space – see and hear how it really sounds, using tools you can use at home.
DIY Solutions for Better Sound
Forget expensive treatments – we’ll walk you through smart, budget-friendly DIY methods to dramatically improve your sound environment.
Discussion & Q&A
Wrap up with an open discussion round for questions, problem-solving, and personal tips tailored to your space.

Death Shanty Audio

Death Shanty Audio focuses on the production of electronic music and sound design. The studio is equipped with a variety of synthesizers, drum machines and effects units, to create a unique sound for each project.

Hamburger Old Villa

The project had it all. When I first met Johannes, the brain behind “Death Shanty Audio”, at an Ableton workshop in Hamburg, he told me about his plan to set up a professional recording studio in the premises of a Hamburg Art Nouveau villa. The extremely exciting floor plan and the asymmetrical vaulted ceiling made the project a very special one. After completing the recording studio, we were both amazed at how much audible detail was possible in combination with the existing charm of the old building.

Cupra Music Labs Frankfurt

In cooperation with mbakustik as project manager, I was able to provide technical and executive support for this extremely complex project.

UNCOMPROMISING STUDIO ACOUSTICS RIGHT IN THE HEART OF EUROPE

Six recording studios on one floor in the middle of Frankfurt's skyscrapers and old buildings. The main studio in particular, Control A, set standards in studio design, as the room-in-room construction using an acoustic design system not only sounds perfect, but also combines acoustics and air conditioning technology almost silently. Two outstanding monitor systems are used in Control A: the Neumann KH420 setup with KH870 subwoofers and the unique Barefoot Masterstack 12. The Barefoot system, calibrated with the support of Thomas Barefoot, impresses with its exceptional resolution, speed and level stability. This setup offers perfect conditions for demanding sound control rooms.
