Working to a very specific brief with only a few days notice to design, test and implement a system very different from the norm, our staff worked with Salford University’s world-renowned acoustic labs to create a system capable of recreating the intense environments experienced by pilots of modern aircraft, so that it may assist in the design of new helmet technologies. Unfortunately a non-disclosure agreement prevents us from detailing the full design specification and response plot that needed to be reproduced, but needless to say it was a task far beyond the needs of your average rock ‘n’ roll concert; particular highlights being the requirement for 115dB of SPL at an incredible 20Hz frequency and around 40 points of parametric equalisation needed to achieve the exact opposite of the traditional ‘flat response’.

We deployed a horizontal array of 8 of our largest custom-built touring subs, the Void Acoustics Psyco Sub, reaching wall to wall in the intended test chamber so that the truly subharmonic frequencies could be assisted by boundary effects (commonly known as ‘corner loading’). These were complimented by a pair of Void Acoustics Stasys Prime mid-high packs, chosen for their ability to reach very high SPL levels with minimal ringing, distortion or beaming. Void Acoustics Infinite 8v2 amplifiers were used due to their ability to bypass the 20Hz subharmonic filter put in place to prevent over-excursion and damage to speakers in normal use.

In addition to this we deployed 4 of OHM UK’s latest TRS Infra enclosures to give the additional boost needed to reach down to the lowest frequencies without the risk of cooking drivers in the process of testing. Several visits were made by our staff over the duration of the test period, not only to assist in the testing procedure itself but to ensure that this seriously intense workout wasn’t putting undue strain on the cabinets, drivers or amplifiers. All equipment held up with not a single failure, despite being required to maintain this truly punishing signal for upwards of 20 minutes at a time, for several days; a testament to the British manufacturing and design involved in creating the equipment used.
