Acoustics and Air Testing Laboratory is a licensed user of ODEON program in Hong Kong. We are available in room acoustics, auditorium acoustics and industrial noise control. ODEON is a famous acoustics program, which provides prediction software for acoustic consultants and universities worldwide.

Room Geometry ODEON provides a 3D view environment for engineer to design and view indoor acoustics condition. Room geometry is being imported from CAD systems. A material list with sound absorption coefficients and transmission characteristic is built in program. Sound absorption coefficients of specified materials can also be input by the users for room acoustics simulation. The room surface can be assigned with different building materials to match the real situation. The sound sources with directivity properties at each frequency band is allowed to locate anywhere inside the room. The receiver can be defined as a whole surface or just a single point which positions by x-y-z coordinate.

Estimated reverberation times in terms of T20 and T30 can be represented as graphical format, and single point response, multi point response and grid response can be mapped in the 3D room surface. Sound field generated by different sound source can be calculated and every sound ray can be tracked; any weak receiving area can be easily identified.

Any modification in geometry or relocation of material will change the room acoustic properties, in order to achieve the best acoustic behaviour; Acoustics and Air Testing Laboratory provides a powerful room acoustics modeling services for Architect, Acoustics Consultant and Sound & AV Designer.
