Introduction

Low-midrange wall bass traps， powerful tool for creating quality acoustic spaces
In acoustic design, the bass trap is one of the key devices for optimising the sound environment. An efficient bass trap is indispensable for places that seek a high-quality sound experience, such as recording studios, home theatres and professional audiovisual rooms. Today, let's take a look at a wall bass trap with dimensions of 1200mm x 400mm x 112mm, absorbing frequencies ranging from 50-500Hz in the low-mid frequency range, and its surface is made of sound-absorbing fabric, which is both practical and aesthetically pleasing.

I. Role of bass trap
Low-frequency sound waves due to the longer wavelength, energy, easy to produce standing waves and resonance phenomenon in the room, resulting in excessive enhancement or weakening of certain frequencies of the sound, destroying the sense of balance and clarity of the sound. Bass traps reduce standing waves by absorbing low-frequency sound waves of specific frequencies, making the sound more evenly distributed in the space, thus enhancing the overall acoustic quality.

II. Product Features
(I) Size and Installation
The size of this bass trap is 1200mm x 400mm x 112mm, with a wall-mounted design, it can flexibly adapt to various room spaces, saving space while absorbing low-frequency sound waves by using the vertical surface of the wall. The installation process is simple, and can be fixed with brackets or adhesives, without the need to make large-scale changes to the room structure.

(ii) Absorption frequency range
The absorption frequency range is 50-500Hz, covering the typical frequency range of low and medium frequency sound waves. Sound waves in this frequency range include the bass part of large instruments (e.g. cello, bass drum) and part of the mid-frequency timbre (e.g. vocals, stringed instruments). By absorbing sound waves at these frequencies, bass traps can effectively reduce standing wave phenomena in the room and improve the clarity and balance of sound.

(iii) Sound-absorbing cloth surface
The use of sound-absorbing cloth material on the surface of bass traps is not only aesthetically pleasing, but also acoustically important. Sound-absorbing cloth can further absorb high-frequency sound waves and reduce the reflection of sound on the surface, forming a double absorption mechanism to enhance the acoustic performance of bass traps. At the same time, sound-absorbing cloth can be selected according to the room style of different colours and textures, so that the bass trap and the environment into one.

Internal structure and working principle
The interior of the Bass Trap consists of multiple layers of sound-absorbing materials, the density and thickness of which are carefully designed to achieve effective absorption of sound waves of specific frequencies. When the sound wave enters the bass trap, the sound-absorbing cloth on the surface absorbs part of the high-frequency components first, and the remaining low-frequency sound wave interacts with the internal sound-absorbing material, which finally converts the sound wave energy into heat energy and reduces the reflection of the sound wave and the generation of standing wave.

Application Scenarios
(I) Recording studio
In the recording studio, the bass trap can effectively absorb low-frequency reflections and standing waves, so that the recording engineer can more clearly capture the real timbre of musical instruments and vocals, avoiding sound distortion due to acoustic problems in the room, and improving the quality of recordings.

(ii) Home Theatre
In home cinema, bass traps can reduce reverberation and resonance of sound, making the movie sound more realistic and shocking, while improving the clarity of vocal dialogue and enhancing the viewing experience.

(iii) Professional audio-visual room
In professional audio-visual rooms, bass traps provide a stable and accurate acoustic environment for audio production and editing, helping professionals to process audio more accurately and improve the quality of works.

Installation and Layout Suggestions
Reasonable installation of the Bass Trap is crucial. It is recommended to prioritise installation in the corners of the room and in the middle of the walls, which are places where low-frequency sound waves are prone to produce standing waves. Depending on the room, sound-absorbing materials can also be added to the ceiling and floor to further optimise the acoustic environment.

VI. Summary
This low and medium frequency wall bass trap is ideal for improving the acoustic environment thanks to its reasonable size and design, wide range of absorbing frequencies and the double absorption effect of the sound-absorbing fabric surface. It can effectively reduce the standing wave phenomenon of low-frequency and mid-frequency sound waves, enhance the clarity and balance of sound, and is suitable for a wide range of acoustic spaces, providing a reliable solution for users in pursuit of a high-quality sound experience.
