Understand Monitor Speakers: The Art Of Spatial Sound

Spatial Sound Configuration

  The principle of sound waves and mirrors are the same and all have reflection characteristics. The sound we heard in the interior space had already been around in the room for a week before it was delivered to our ears. Some of these sound waves will gradually increase after reflection, while others will be suppressed; different sound wave changes will change according to their characteristics. Any plane (blackboard, wall, ceiling, etc.) may cause abnormal reflection of sound waves. Therefore, when selecting a monitor, you should be careful about the material used for the sound insulation. And by correcting the sound reflection in the space with the correct sound settings, you can greatly enhance your listening environment.

  Many people use the extra space in the bedroom or other square pattern as a recording studio. Unfortunately, when the walls in space appear parallel, so-called "standing waves" often occur. This phenomenon occurs when the “synchronous cancellation” phenomenon caused by the reflection of sound waves from another parallel interface interferes with the amplitude of sound waves in space. Although this type of sound setup will cause many problems, it is feasible to turn a square pattern space into a correct monitoring sound configuration. This means that you can make adjustments and understand the sound characteristics of space. The effect of sonic reflections is minimized.

  Tips: All the sounds we hear in our ears are the result of a combination of direct transmission and reflection transmission. The reflection of sound waves not only enhances their own frequency, but also reduces the frequency of other sound waves. You can sit close to the monitor speakers or position the monitor speakers closer to you, so that you can hear more directly transmitted sound waves and receive less reflected sound waves.


Sound Configuration Processing

All indoor spaces require some degree of acoustic configuration. Sometimes you only need to arrange a simple sound configuration by carefully laying out sofas, bookshelves and other interior furniture. However, in most cases, effective elimination of acoustic reflections must rely on materials that have sound-absorbing effects and prevent the diffusion of sound waves. The proper acoustic configuration processing can effectively reduce the acoustic reflection frequency of indoor space while eliminating unnecessary echoes.


Sound Absorbing Device

The purpose of installing the sound-absorbing device is to offset some of the annoying sound waves reflected by the sound-absorbing material, and the sound-absorbing device cannot achieve the effect of complete sound insulation. Like heavy fabrics, fiberglass, sound-absorbing foam - these materials have the effect of absorbing medium-high-frequency sound. These materials can be easily attached to the wall or ceiling, while effectively reducing the sound wave reflection. Approximately two inches of sound-absorbing foam can absorb approximately 500 Hz of sound—while four inches of sound-absorbing cotton absorb only about 250 Hz of sound. After preparing the sound-absorbing material, first check any potential sound reflection points in your listening environment that may reflect the sound waves. Then check whether there is any plane that is easy for the sound wave to reflect towards the listening position. Generally, the walls behind the side wall, back wall, and monitor speaker are most likely to cause problems. These areas should be equipped with sound-absorbing fabrics.

  Tips: You can install the sound-absorbing cotton on the plywood. The wall can hold about 4 to 6 inches of sound-absorbing cotton. It can effectively enhance the listening environment without changing the wall surface. In addition, you can even record the vocal part by resetting the splint to install a temporary soundproof room.
