SCHOKOLADEN

About the project
The Schokoladen is a long-established cultural venue in Berlin-Mitte and has been an important part of the city’s independent cultural scene for many years. Located in a former factory building, the venue hosts concerts, parties and other cultural events.

Initial situation
The stage in the event space was originally not structurally separated from the rest of the building. As a result, particularly low-frequency vibrations were transmitted through the building structure, causing significant noise pollution in the neighbouring apartments. The apartments directly next to and above the venue were particularly affected.
Following repeated complaints from the neighbourhood, a soundproofing report was commissioned to analyse the causes of the sound transmission and identify suitable measures. Based on its recommendations, the impact sound insulation of both the floor structure and the stage structure was renewed.

Measures

1. Renewal of the floor insulation
The impact sound insulation of the existing floor structure was renewed to reduce sound transmission, particularly in the low-frequency range.

2. Renewal of the stage structure
The impact sound insulation of the stage structure was also renewed to further reduce the transmission of vibrations through the building.

3. Recalibration of the technical equipment
The existing technical equipment was dismantled to provide access to the stage area during the construction work. After the structural measures had been completed, the equipment was recalibrated and sealed.
The work was completed as planned without any difficulties or delays and without requiring a longer closure of the venue.

Result
The measures led to a significant reduction in sound transmission to the neighbouring apartments. Feedback from the neighbourhood confirmed that low-frequency noise in particular is now much less perceptible.
The project therefore improved the sound insulation of the stage area and reduced the impact of sound transmission on the surrounding residential area.
