When information is being communicated to an audience it is very important that the speaker can be heard clearly.

Developed for classrooms and open-plan offices

If you are looking for a ceiling that promotes speech intelligibility, tests have shown that Master/alpha is in a class of its own. It has excellent sound absorption for frequencies above 250 Hz and also provides high absorption for low frequencies. Therefore, Ecophon Master/alpha is particularly well suited for rooms where maximum absorption throughout the frequency range is desirable, such as classrooms and open-plan offices. It is also ideal in areas where there is low-frequency disturbance from ventilation systems or external sources such as traffic noise.

Ecophon Master variations for different situations

Wall-to-wall solution:

Master gamma products with edge design B, C, D or F installed wall-to-wall when combined with corresponding Master alpha products.

Island solution:

Master gamma products with edge design A or E can be installed as an area in the middle of the ceiling when combined with corresponding Master alpha products.

All Ecophon Master systems are available with three different sound absorption characteristics, which can be used separately or in combination depending on the room type. For detailed information see Functional demands, Acoustics.

alpha - the surface that produces the highest sound absorption - class A - used for wall-to-wall ceilings in open-plan offices, lecture rooms and conference halls with floor areas up to about 100 m², possibly combined with Master gamma.
beta - suitable for installation as a full ceiling in music rooms with floor areas up to 100 m². Due to its reduced high-frequency sound absorption - class C - it offers greater tone richness.
gamma - has a sound absorption capacity for low frequencies only and is otherwise a sound reflector - sound absorption class E. Master gamma can be used with Master alpha in lecture halls with floor areas of more than 100 m². It can also be used to give fast feedback to the speaker.
extra bass - is a complement to Master/alpha when increased sound absorption is required, especially in the low frequencies. It is very important for people with hearing impairment.
