Не знаю, по теме ли мой ответ, но есть отличная программа для расчета акустики помещений Cara. Вот что она может:
-Room Design
-Room Acoustic Calculations
-Presentation of Results (2D and 3D Diagrams)
Room Design:
arbitrary floor plans (L-rooms, coupled rooms, ...), maximum size 100 x 100 m, the wizard "New Room Design" offers a number of predefined floor plan templates (all dimensions may also be entered in non-metric units like inches or feet)
inside walls as partitions, columns, false ceilings, ceiling beams, as well as sloped ceilings and oblique floors (attic apartments, cinemas)
furniture database (tables, cupboards, armchairs, etc.), or customize your furniture of several so-called 3D-objects
additional sound absorbing sub areas (windows, pictures, carpets) can be defined within a wall
Materials Editor: definition of customized sound absorbing materials
Loudspeaker Editor: customize your loudspeaker model (cabinet styles : blocks with slanted walls), 1-5 ways loudspeakers, act./pass. subwoofers, or dipole radiating flat panels. Using the updated (Rel. 2.2 PLUS) editor (see Download / Patches) also sophisticated cabinets (e.g. composed of several cabinet sections, like a dipole hybrid LS) may be designed.
Loudspeaker Configurations: Stereo, Quadro, Surround (analogue, digital: 5.1, 6.1, 7.1, 8.1), PA (Public Address), any number of subwoofers
loudspeaker database with approx. 200 proprietary speaker models, new models can be "downloaded" from the internet
Positional Optimization: L-, T-, or cross shaped positioning regions
walking around in your 3D room model
Calculations:
automatic positional optimization for the loudspeakers and the listening place, with symmetry constraint options (equal spacing to front and side walls)
room sound field calculations at 1000-3000 grid points equally distributed within a certain layer above the floor
reduction of calculating times for rectangular rooms (without furniture) in comparison to the latest version by a factor of up to 1000
calculation with real and complex reflection coefficients (optionally)
The additional "PLUS Functions":
Calculation and evaluation of the "Acoustic Ambiance" (reverberation time spectrum)
Calculation of the high resolution transient room response as a basis for the "Auralization" (listening test)
Presentation of Results:
representation of the optimized positioning of the loudspeakers and the listening place
listing of a survey of the room acoustics reference numbers: sound coloration, location, speech intelligibility, reverberation time and lateral sound level
3D representation of the frequency and time dependence of the modal structure of the sound pressure in the room
3D representation the temporal propagation of the sound wave fronts in the room
3D sound coloration, location and speech intelligibility maps of your sound room
2D-XY diagrams: sound pressure level frequency responses, location diagram, reverberation diagram, frequency dependence of the mean sound absorption coefficient and of the reverberation time (Sabine, Eyring, Kuttruff and CARA-T10) of your room
The additional "PLUS Functions":
"Acoustic Ambiance" including suggestions for linearizing the reverberation time spectrum by insertion of additional materials or furniture (already during room design)
"Auralization": listening tests e.g. for the comparison of different loudspeaker positionings
