Engineering services for room acoustics and electroacoustics

We measure and optimize room acoustics and ensure clear speech intelligibility

In room acoustics, the aim may be to enable sweet sounds or to avoid an acoustic nightmare: No matter whether it's about the clean sound of the first violin in the box seats or, in the worst case, an emergency announcement, which must be understandable even in the last corner of a burning large-scale facility: Wölfel is your consultant for room acoustics, optimizing any kind of room on the basis of measurement, calculation and simulation.

We have answers to your concerns such as:

  • How do you ensure audibility in a turbulent classroom?
  • How can the voice of the stadium announcer be heard clearly even in the back seats?
  • Can announcements be understood well even on a moving train on a bumpy track?
  • How can the best sound be achieved in the new concert hall?

The acoustic conditions of a room have a decisive influence on its usability and general well-being: For example, improving the room acoustics in the office does something for the health of the employees as well as their productivity; acoustically renovating an old university building from the 19th century significantly improves the absorption of knowledge.

If a room is furthermore equipped with an electro-acoustic system, the room acoustics are decisive for the achievable sound quality.

We support you in developing a room acoustic design that is optimized with regards to the functionality of the rooms. For this purpose, we use both classical calculation approaches and modern simulation methods. Our services also include complex planning of sound reinforcement systems to ensure the supply level and speech intelligibility in public buildings.

Our services

  • Design and acceptance of sound reinforcement systems according to DIN VDE 0828/0833-4
  • Planning and acceptance of rooms in accordance with DIN 18041
  • Forecast calculations, acceptance measurements and optimization of speech intelligibility (STI) according to DIN EN 60268-16


     
  • Preparation of target specifications for acoustics
  • Reverberation time measurement according to DIN EN ISO3382
  • Room acoustic design, e.g. optimization of the reverberation time through sound-absorbing measures or use of reflecting planes for targeted sound propagation
  • Room acoustic simulation on a computer model
  • Measurement of the sound absorption coefficient, wall impedance and reflection factor according to DIN EN ISO 10534-2

Available to you in every project and planning phase

This is how we solve your building acoustics challenges together – step by step:

  • Make contact in every project phase
  • Call-back from our specialist engineers: We assess your challenge and jointly agree on the scope of services on the basis of, among other things, the project documents
  • Preparation of a free, non-binding offer
