Unlike sound absorption panels that are made of soft materials with lots of air pockets that prevent sound waves from bouncing back at you, a sound diffuser allows for the sound to reflect-but it breaks up the reflection so you don’t get a clear echo. When you hear an echo, that’s a sound wave bouncing off a surface and coming back to you. High pitched sounds have shorter wavelengths than deep, bass sounds. A sound’s wavelength varies depending on its pitch. That’s why your voice echoes more in some rooms than others.Īnother element of sound is that it comes in waves. Sound does the same thing, except every hard, flat surface can serve as a mirror for it. When you shine a light at a mirror, the light reflects back at you. In some ways, sound operates kind of like light. or anything, but some knowledge of the basics will give context.
To understand what a sound diffuser does, you need to first understand a few principles of the physics of sound. Often what you need is a well-placed sound diffuser.ĭiffusing sound can be harder for a layperson to wrap their head around than sound absorption, but it is essential to creating a sonic experience that is rich and full instead of flat and sterile.Įffectively using sound diffusers requires understanding not just what they are, but where to place them in a room to get the best results-no matter if you are listening for business or fun. Making a great listening environment isn’t necessarily a matter of soundproofing a room. “Good sound” often comes just as much from the listening environment. It isn’t just the quality of the music or the sound mixing in a movie.
Walls used in the model are considered to be perfectly reflecting and at 1 metre distance (facade level).The noise source behaves as a point source and is far-field, where inherent directivity is minimal.There are no affecting weather conditions, such as wind or temperature inversion, as these will affect the propagation path of a noise source and diffraction around the barrier.In reality when dealing with short distances and many reflective surfaces the "canyon effect" may occur with repeating reflections. There are no reflections from the barrier.
No transmission of sound through the barrier - therefore, the total transmission of sound through the barrier must be at least 10dB below the level of sound transmission above the barrier.No transmission of sound around the barrier - therefore, the combined transmission of sound around the sides of the barrier must be at least 10dB below the level of sound transmission above the barrier.
