Standing waves in the room: where they come from and how to deal with them

Briefly: Standing waves in a room are caused by sound waves reflecting off the walls, floor, and ceiling. To combat them, it is necessary to conduct a 3D scan of the room and design an acoustic system that takes into account the modal map and the geometry of the boundaries.

Acoustics frequency standing waves is a serious problem faced by many music lovers and audiophiles. Standing waves occur when sound waves emitted by speakers bounce off walls, floors, and ceilings and create interference patterns that can significantly affect sound quality.

Where do standing waves come from?

Standing waves arise from the reflection of sound waves from walls, floors and ceilings. When a sound wave hits an obstacle, it is reflected and creates a standing wave, which can be either constructive or destructive. Constructive interference occurs when two waves add together, creating a stronger wave, while destructive interference occurs when two waves subtract, creating a weaker wave.

How to deal with standing waves?

To combat standing waves, it is necessary to conduct a 3D scan of the room and design an acoustic system that takes into account the modal map and boundary geometry. This allows you to determine the optimal placement of speakers and acoustic elements to minimize standing waves and improve sound quality.

In our projects we use our own active 3-way Payos Audio Main Control monitors, which provide accurate and detailed sound. We also use the impulse response method (Dirac function), which allows us to obtain a complete correlation between objective measurements and subjective perception.

Frequently asked questions

What is the cause of standing waves?

Standing waves arise from the reflection of sound waves from walls, floors and ceilings.

How can you deal with standing waves?

To combat standing waves, it is necessary to conduct a 3D scan of the room and design an acoustic system that takes into account the modal map and boundary geometry.

What methods are used to measure standing waves?

We use the impulse response method (Dirac function) and 3D scanning of the room.

Can the standard Thiel-Small method be used to measure standing waves?

No, the standard Thiel-Small method (1965, sine signals) gives an efficiency of 1.5-5%, which is not enough to accurately measure standing waves.
