3 USER SUPPORT
A large number of consultants at Marshall
Day Acoustics use SoundPLAN on a daily basis, therefore we have a wealth of user
knowledge to draw upon to assist in solving user-related issues.
We offer on-going telephone and e-mail support and in-house training for SoundPLAN users – at our office or yours.
4 IN-HOUSE SOFTWARE
Marshall Day Acoustics has developed a
number of high quality acoustical design tools that are in use by acoustics
professionals on every continent.
INSUL is a program for predicting the sound insulation of walls, floors, ceilings and windows. The program can estimate the Transmission Loss (TL) in 1/3 octave bands and Weighted Sound Reduction Index (STC or Rw) for use in sound transfer calculations.
ZORBA is a quick tool for predicting the absorption performance of porous systems with perforated facings. This tool is ideal for the investigation of acoustically critical rooms such as studios, concerts halls, class room, lecture theatres and others.
