Dependability
Eckel's architectural noise control panel systems are designed to provide effective control of reverberation and background noise in any
architectural application from a small classroom or gym to a large coliseum, water treatment facility or industrial plant. Eckel's designs offer
the architect or acoustical consultant a range of products to select from to satisfy almost any noise control requirement in a wide range of
applications. With over forty years experience in noise control, Eckel can provide a standard system or custom engineered design and
guarantee the results.
Service & Support
Engineering support services include acoustical analysis of building spaces. Room reverberation time calculations are offered as a service
to architects and engineers utilizing our computer model room noise analysis program. Eckel can measure before and after room
reverberation time and noise levels in a full range of frequencies from 125 Hz to 8,000 Hz when needed for correction of problems in existing
facilities. Complete turn-key design, layout, engineering and installation are available.
