Acoustic Treatment and Design for Recording Studios and Listenin

Ethan has at various times earned a living as a professional musician, computer programmer, circuit designer, recording engineer, composer/arranger, technical writer, acoustician, and college instructor. Ethan has more than 150 feature articles published in various computer and audio magazines. He’s produced dozens of educational and music videos, and composed three pieces for full orchestra, all of which have been performed.

Untitled Document. Acoustic. Sound is conveyed through waves in the air.


Waves that exist between a pair of surfaces can create standing wave resonances whenever the distance between the surfaces is any even multiple of one-half of the wavelength. At resonant frequencies (tones), the sound is louder and decays much more slowly than at non-resonant frequencies, causing uneven tonal quality and interference with clarity. Resonant frequencies occur mainly in the bass range, due to the relationship between the wavelengths of low-frequency sounds and the typical sizes of listening rooms. Every room has its associated resonant frequencies. Rooms built using preferred dimensions ratios have potentially more even distributions of these resonant frequencies. Room built with angles walls or ceilings have more complicated resonant modes than typical rectangular rooms and the resonances can be potentially less severe.

Room Acoustics Calculator. The Room Acoustics Calculator enables you to design the acoustics of a room according to DIN 18041 and ÖNORM B 8115-3. After the usage and the appropriate standard have been selected the calculator derives the relevant design quantities, tolerance ranges or limits, and the corresponding state of the room (furnished, unfurnished, occupied or unoccupied). Where a room is required to provide good audibility over greater distances, such as, for example, in a lecture hall, both standards require compliance with a reverberation time T within a given tolerance range. For rooms where the main issue is noise reduction, and good audibility is only desired over shorter distances as, for example, in open plan offices, different design quantities are defined in the two standards. DIN 18041 uses the noise reduction ΔL and an average absorption coefficient α–of the room’s surface area.

Acoustic Basics

Yet many recording enthusiasts, unhappy with the quality of their productions, wrongly blame their gear. Of course, experience matters, but so does having accurate acoustics. This "Tip Jar" article from Music Connection magazine explains the basics of acoustics in a way that everyone can easily understand. All of the information herein also applies to audiophile and home theater listening rooms. Bass frequencies are the most difficult to tame in the small rooms many people use to record and mix their music. Since you hear less bass than is really in the track, you add too much bass with EQ to compensate.

ROOM ORIENTATION AND SPEAKER PLACEMENT In a standard rectangular room, it's best to orient the mix position so the speakers are firing the longer way down the room. Welcome to ETF Acoustics.
