APH’s noise metering and analysing service is aimed at the event industry. We will produce a full assessment to ensure that your event or production is compliant to licensing regulations.
Noise pollution from events is increasingly being included in the licensing procedure. It is essential that noise management is considered from the earliest stages of event planning. APH will liaise directly with the client and associated Noise Management Company, and if requested with the local authorities throughout the whole process compiling comprehensive reports to support the noise management plan. The PA system design works hand in hand with the noise management plan. From careful modelling of the area, APH can design a system that meets all licensing conditions and minimises disturbance whilst providing maximum sound quality to the audience.

PA System Design
APH don’t just restrict the noise level from a venue or outside event by turning the volume down, instead through design, the system will concentrate on reducing unwanted sound spill whilst giving the audience the required sound level. This is achieved by bespoke sound system configurations within the noise management software to control certain frequencies, directing the sound to the audience area only.
Deployment of our DAS Audio systems, Audio Production Hire acoustic design noise management engineers can use DASaim FIR sound steering technology to focus sound on the audience, cancel it going backwards or to the side, or even create “strong avoid” sections where the sound is reduced using advanced FIR filter technology.
This holistic approach to noise management gives much better results than simply turning the volume down and allows satisfaction for the audience, the noise management team and the council’s environmental officers.
DASAIM TecHnology
DASaim™
The DAS Audio engineering team has been working on adapting FIRmaker solution of AFMG to the AERO-20A and AERO-40A systems.
The result is a software solution that empowers DAS users and takes the AERO-20A and AERO-40A systems to a whole new level.
“Thanks to the powerful DSP built into the amplifiers of each AERO system, no external multi-channel processors are needed in order to have one FIR filter per cabinet. This means greater simplicity and a significant reduction in investment and set up time when compared to other solutions on the market” – Javier Navarro, Head of Engineering DAS Audio.

Technical information
With DASaim™ technology you can achieve your desired goals in seconds:
Controlled SPL level with distance: from constant SPL to -6dB per double distance
Frequency response uniformity for the whole audience
Digital steering of the vertical radiation pattern of the array to the listening areas
Reduce the SPL in areas to be avoided like the stage or unused balconies with a few clicks
Simplify and speed-up your design and set-up times
Improve intelligibility
Improve and make your array more flexible without the cost of external processors, processed amplifiers, or extra cabling
One FIR per cabinet means maximum space resolution and control up to higher frequencies
