Celebrating 40 Years in Acoustics

Computer modelling of internal spaces using EASE software provides a visual, qualitative and quantitative insight into the acoustics of rooms.

Computer modelling is used to acoustically design the interiors of halls, lecture and drama theatres and auditoriums. Three dimensional modelling facilitates the design of surfaces and shapes within rooms to achieve design reverberation times and to ensure that high levels of speech intelligibility are achieved. We design halls, theatres and auditoriums using a range of acoustical quality parameters to optimise performance.

An example of a drama theatre is shown of arrival time (in milli-seconds) of speech from a sound source on the stage. Other parameters such as clarity; a ratio of direct to reverberant and total sound pressure and direct sound pressure levels can also be determined. These indexes are used to optimise the shape of the room and the location of reflectors and absorption elements to ensure that people in any location can clearly hear voices on stage.

Noise Monitoring - 24/7 back-to-base and real-time

More often than not, noise measurement is needed when you can’t be there.

AND the question is always, what sort of noise was recorded?

Now there’s a better way.

It’s our state of the art noise monitor that’s remotely operated over the internet.

The all-weather unit operates using battery/solar power and can be left indefinitely with remote periodic calibration of the Class 1 analyser.

It can be remotely triggered anytime or at nominated threshold levels.

It stores and transmits comprehensive noise statistics, spectra and audio recordings making noise source identification easy.

Data is sent through a 3G wireless broadband field-grade modem.  It’s usually controlled by a PC although an iPhone can be used.

AND now it’s possible to integrate the real time measurement results of remote access monitoring with SoundPLAN providing a previously unbelievable degree of information across noise catchments and time profiles. 

Its use will result in significantly more useful, accurate and relevant noise data.
