The natural room sound captured by microphones plays a decisive role in every recording. Yet in many home-recording setups, this topic receives far too little attention. Even small acoustic adjustments can lead to surprisingly noticeable improvements and significantly enhance the quality of your recordings.
Acoustic treatment is often confused with soundproofing, but these are two completely different concepts. Soundproofing reduces sound leaking out of a room, while acoustic treatment focuses on optimising the sound within the room itself—for better results when playing, rehearsing or recording.
Many musicians know the scenario: the band is ready, everything is set up—and as soon as the drums kick in, the room becomes unpleasantly loud. Bare, parallel walls intensify the reverb. Quick fixes like egg cartons offer virtually no improvement. What really matters is controlling and reducing unwanted reflections.
Every room has its own acoustic character. Famous studios like Abbey Road or Hansa Berlin are legendary partly due to their unique room sound. Software companies measure these spaces and create impulse responses to digitally recreate their acoustics.
Walls, floors and ceilings all contribute to the sound. An acoustic guitar will sound different in a wooden room compared to a heavily damped room with thick curtains. The desired amount of reverb depends on the use case: acoustic instruments often benefit from a more lively space, whereas spoken-word recordings require a dry, controlled environment.
Your listening and recording position also plays a key role. Problematic bass buildups often occur in corners. A measurement microphone can help visualise these issues so they can be addressed correctly.
Heavy curtains absorb sound, packed bookshelves scatter it. These simple measures can already help—but for a clean, controlled and professional room sound, dedicated acoustic elements are used. The most important are absorbers, bass traps and diffusers.
If a room has excessive reverberation, absorbers are the first step toward improvement. Broadband absorbers reduce reverb across a wide frequency range, as sound energy is captured in the porous material and converted into heat. In general, the thicker the absorber, the lower the frequencies it can effectively treat.
Well-placed absorbers can significantly reduce reverb—a common issue in rehearsal rooms and small studios.
Small rectangular rooms often suffer from excessive low-frequency buildup, especially in corners. Bass traps are placed directly in these areas and can be stacked to increase their effect. Their higher material density allows them to effectively tame deep frequencies and improve bass clarity.
Diffusers work differently from absorbers. Instead of absorbing sound, they disperse it evenly throughout the room. Their irregular surfaces break incoming sound waves into many smaller components, reducing flutter echoes, standing waves and harsh frequency peaks.
The result is a more open and lively room sound without becoming overly reverberant—ideal for acoustic instruments and overly “dry” rooms. Even a fully packed bookshelf can act as a natural diffuser.
Diffusers enhance room liveliness and effectively reduce flutter echoes.
For anyone new to acoustic treatment, starting gradually is best. Even a small number of strategically placed absorbers or bass traps can produce noticeable improvements. The ideal amount of treatment depends on the room’s size, shape and intended use—there is no universal percentage guideline.
For more advanced studio work, consulting an acoustics specialist may be useful. Beyond absorbers, bass traps and diffusers, additional solutions such as portable reflection screens or hybrid acoustic modules are available for optimising specific situations like vocal booths or project studios.
Reflection screens like the MRS can significantly improve vocal and speech recordings in untreated rooms.
A reflection filter surrounds the microphone from multiple sides and reduces unwanted reflections and room sound. This results in a clearer, more focused signal—ideal for vocals, speech, podcasts or voice-over work in untreated or reflective environments.
A reflection filter can greatly enhance vocal and speech clarity in home or project studios.
When studio monitors sit directly on desks or shelves, these surfaces often resonate and colour the sound. Speaker pads isolate the monitors from the surface, reducing unwanted resonances and improving bass precision.
The pads are made from high-density foam and often offer several angle options to position the speakers correctly. Even this simple upgrade can significantly enhance stereo imaging and low-end accuracy.
Speaker pads isolate your monitors from the surface—greatly improving bass accuracy and overall clarity.
