We develop high quality acoustic design tools that are used globally by scholars, consultants, designers and manufacturers.
We are continually looking to improve our services, expand our technical expertise and develop our equipment and systems in order to provide you with the most comprehensive and cutting edge design tools.
dBWav is a powerful and user-friendly tool for analysing audio files. It comfortably handles processing of large files and long term recordings, offering a high-level review of data sets for quick identification of features and trends.
dBWav is specifically tailored for hydrophone recordings and it is compatible with Ocean Instruments SoundTrap hydrophones.Read more
INSUL is a program developed for predicting the sound insulation of walls, floors, ceilings and windows.
INSUL can estimate the Transmission Loss (TL) or Sound Reduction (R) in 1/3 octave bands along with weighted indices (STC or Rw) for use in sound transfer calculations. INSUL can also be used for estimating 1/3 octave band Impact Sound Pressure Levels and associated indices (IIC or Ln,w) as well as levels of rain noise.
INSUL has a simple and easy-to-use interface which can be used to quickly develop performance estimates for a diverse range of wall, floor, roof and glazing constructions.
An overview of prediction theory, comparisons to actual constructions and a demonstration version of INSUL are all available at the INSUL website.Visit the Insul website
IRIS is a powerful and user friendly measurement system for capturing and analysing room impulse responses in 3D.
The IRIS plot is at the heart of the IRIS system. Sound rays arriving at the measurement position are represented as a series of easy to identify coloured spikes, immediately after the measurement is conducted.
The IRIS plot can be used to relate sound rays to physical features of the room, observe the directional distribution of early and late sound energy, as well as identify surfaces causing problematic reflections.
dBSea has been developed by Marshall Day Acoustics as a powerful tool for the prediction of underwater noise in a variety of environments. dBSea is ideal for the investigation of underwater acoustic problems involving single or multiple sources using solvers covering a wide frequency range.
dBSea incorporates a user friendly interface and clearly defined workflow that allow models to be quickly developed and modified. The 3D workspace allows clear visualisation of bathymetry data, noise sources and prediction results.Visit the dBSea website
ZORBA is a quick, easy-to-use tool for predicting the absorption performance of porous systems with perforated facings.
ZORBA is ideal for investigating the finishes in acoustically critical rooms such as studios, concerts halls, class rooms and lecture theatres.
An overview of ZORBA's prediction theory, comparisons with test data and a demonstration version of ZORBA are all available at the ZORBA website.Visit the Zorba website
