Diffusers

Diffusers scatter sound waves to create an even sound distribution and a livelier sound image. These acoustic elements prevent strong reflections and flutter echoes without “drying out” the room. Diffusers are ideal for recording studios, control rooms and home theaters where natural and balanced acoustics are desired.

What is a diffuser?

A diffuser is an acoustic module that scatters sound waves to control reflections and improve the sound quality in a room. Unlike absorbers, which reduce sound energy, diffusers retain the sound energy and distribute it evenly in different directions. This prevents standing waves and flutter echoes and ensures an even and natural sound reproduction.

Diffusers are important for improving the acoustic quality of a room, especially in studios, home theaters and other audiovisual environments. They offer the following advantages:

  • Reduction of standing waves: Prevent the formation of standing waves that can distort the sound.
  • Improved surround sound quality: Maintains the natural liveliness of the sound by distributing it evenly throughout the room.
  • Avoidance of flutter echoes: Eliminate fast, repeated echoes between parallel walls.
  • Increased clarity: Ensure clearer and more detailed sound reproduction by diffusing sound reflections.

A diffuser works by scattering sound waves that hit its surface in different directions. This is achieved by the complex geometry of the diffuser, which consists of surfaces of different depths and widths.
These structures cause the sound waves to be reflected and scattered instead of being thrown back directly. This distributes the sound evenly throughout the room, resulting in a more natural and balanced sound environment.

There are various types of diffusers that differ in design, material and function:

  • Quadratic Residue Diffusers (QRD): Use a mathematical sequence to determine the depth of the individual elements and thus scatter sound waves evenly.
  • Skyline diffusers: Have a three-dimensional surface with towers of different heights that scatter sound waves in different directions.
  • Poly diffusers: Consist of curved or cylindrical surfaces that spread sound waves over a wide area.
  • Hybrid diffusers: Combine diffusion and absorption in one device to control both high and low frequencies.

The most important features of good diffusers are

  • Design: Complex and precise geometry that ensures effective sound dispersion.
  • Material quality: High-quality materials that are durable and effectively diffuse sound.
  • Application range: Suitable for the frequency range you want to control.
  • Aesthetics: Attractive design that fits well into the room.
  • Mounting options: Easy to install and place in various locations in the room.

When choosing the right diffusers, you should consider the following factors:

  • Room size and shape: Determine how many diffusers you need for your room.
  • Frequency range: Think about which frequencies you want to control (high, medium frequencies).
  • Design and material: Choose diffusers with the right geometry and material quality for your needs.
  • Positioning: Determine where the diffusers can be placed most effectively, e.g. on the walls or ceiling.
  • Aesthetics: Make sure that the diffusers fit well into the room and are visually appealing.

Important accessories for diffusers include:

  • Mounting systems: Brackets, rails and clips for securely fastening the diffusers to walls and ceilings.
  • Acoustic fabrics: Fabrics for covering the diffusers to make them visually appealing.
  • Combined elements: Diffusers combined with absorbers to provide a more comprehensive room acoustics solution.

To use diffusers effectively, follow these steps:

  1. Identify problematic areas: Determine the places in the room where standing waves and flutter echoes occur.
  2. Placement: Place diffusers on the rear walls, side walls and ceilings to disperse the sound waves evenly.
  3. Measure: Take room measurements before and after installation to assess the actual effectiveness.
  4. Testing: Listen to recordings before and after installing the diffusers to assess the difference.
  5. Fine-tuning: Adjust the placement of the diffusers if necessary to further optimize the acoustics.
  6. Combination with absorbers: Use absorbers in combination with diffusers to achieve balanced room acoustics.

To maximize the effectiveness of your diffusers, you should consider the following points:

  • Targeted placement: Place the diffusers on the rear walls, side walls and ceiling to achieve even sound dispersion.
  • Combination with absorbers: Use absorbers in combination with diffusers to achieve balanced room acoustics.
  • Regular acoustic measurements: Carry out acoustic measurements after major changes in your room to check and adjust the effectiveness of the diffusers.
  • High-quality materials: Use high-quality materials and products to ensure the best possible spreading performance.
  • Room design: Consider the entire room design, including furniture and other elements, to optimize the acoustics.

The most common mistakes when using diffusers are:

  • Uneven distribution: If diffusers are distributed unevenly in the room, this can lead to uneven sound scattering.
  • Incorrect placement: If diffusers are not placed in the right places, they are less effective.
  • Too few diffusers: An insufficient number of diffusers cannot improve the acoustics sufficiently.
  • Neglecting absorption: Diffusers alone are not enough; a combination with absorbers is usually necessary.

The benefits of using diffusers include:

  • Improved sound quality: Diffusers scatter sound waves evenly throughout the room, resulting in clearer and more precise sound reproduction.
  • Reduced echoes and reflections: Diffusers minimize unwanted echoes and reflections that can affect sound quality.
  • More natural sound: The even sound dispersion makes the surround sound more natural and less “muffled”.
  • Aesthetic enhancement: Diffusers can also be visually appealing and improve the design of your room.

The main difference between diffusers and absorbers lies in their function:

  • Diffusers: Scatter sound waves in different directions to reduce standing waves and flutter echoes without reducing the sound energy. They improve the spatial distribution of sound and maintain the liveliness of the room.
  • Absorbers: Reduce sound energy by absorbing sound waves and converting them into heat. They are effective in reducing reverberation and reflections.
