The design philosophy behind the production of every new product at Peecker Sound's Research and Development Department is rooted in over thirty years of acoustic analysis, testing and continuous innovation.
The best way to summarize the approach is to subdivide it into the following two distinct themes:
A) The design philosophy of a sound reinforcement system
It sets out from considerations regarding:
1) the required areas and levels of sound delivery;
2) the type of use of the installation, depending on the kind of event for which it is required.
With regard to point 1), the distinguishing feature of Peecker Sound as compared to generic manufacturers is that our systems are designed to generate sound waves exactly for where they are needed. The company applies a dedicated acoustic room filling approach, i.e. filling acoustically only selected dancing or listening areas, thereby creating other areas called “decompression zones” with lower exposure to sound pressure, in compliance with the various Italian anti-decibel legal requirements. The sound coming from a speaker standing five metres away from the receiver and the sound coming from the same speaker, but located sixty metres away, is obviously different. Hence, the speakers designed and used by Peecker Sound are generic, but they have specific radiation areas.
As far as point 2) is concerned, it should be noted that our company uses various analogical-digital devices such as crossovers, equalizers, processors and limiters to control the sound system electronically, so that the speakers can be adjusted and set up to achieve maximum performance for every kind of music and to match the sound delivery requirements of every type of event.
B) Designing a loudspeaker system
When designing loudspeaker systems, Peecker Sound has to take into account the various short-range (Upturned T series), medium-range (Forty series) and long-range (Special Speakers) sound system requirements.
The design is affected by the following technical-decisional variables:
• the dispersion angle, which has to be constant for all frequencies (see the image below – note that the timbre of the sound 'message' delivered in the area shown has to be the same throughout!);
• the filters, which are constantly renewed and whose extremely sophisticated design eliminates any possible distortion in the musical signal (and not just test signals at the commonly adopted sinusoidal regimes!);
• the frequency response – all Peecker Sound speakers have a uniform response in terms of both amplitude and phase;
• reliability – speakers are tested through FMEA techniques and undergo a lengthy acoustic testing process. Peecker Sound uses extremely heat-resistant components, armoured resistors and oversized components. Moreover, the mechanical structure of the speakers is rigid and vibration-free. |
