Given the nature of the telephone and switchboard operations, this presented an unprecedented design challenge from an acoustic perspective. How could such a fluid space be achieved in a high density, high call volume environment, where call quality was crucial to business performance and customer service?

The ideal solution was found in the CMS SuperPhon range from CMS Danskin Acoustics. Working closely with the architects, CMS Danskin Acoustics undertook a completely bespoke design process which balanced aesthetics with installation practicalities. For example, some panels were installed with a demountable fixing system to allow access to services behind ceiling rafts. Moreover, in other areas radii was applied to the corner panels so that they could follow the curvature of the wall.

A staggering 2,500 wall panels were installed over the two operational storeys of the new building, with a total contract value of £200k. From an aesthetic perspective, CMS Danskin Acoustics delivered a highly varied range of finishes and colours, from funky and bright patterns through to highly creative gooseberry fruit prints for Ed’s own office.

As a truly acoustic-led building design brief, Moneypenny has broken new ground and demonstrated in a live environment that the seemingly impossible can be achieved: “I’ve been told that we’ve defied the laws of acoustics in some ways, but it just goes to show that breaking from the norm can actually create a better way. The new development and the acoustic quality we have achieved is living proof of that!”

When Veitchi Interiors, responsible for the venue’s acoustics, discovered that the bespoke sound absorption panels specified for the job were accompanied by an unacceptable lead time, the search was on for a viable alternative. The replacement product not only had to be fabricated and delivered to a demanding schedule, it also had to meet specific technical criteria as guided by acoustic consultants, Sandy Brown Associates. It had to be a Class 0 product, conforming to BS 476 Parts 6&7. Acoustically, it was vital that the new product performed to BS EN ISO 354:2003. And because the product was to be used to line the walls and balustrades in the audience area, where the panels would be fully exposed to the potential for repeated and significant physical impact, the product had to perform to DIN 18032-3 for impact resistance and EN 15312 for rigidity.

A replacement product was soon found in the form of CMS Danskin Acoustics’ SuperPhon High Impact sound absorption panel. CMS Danskin’s product was available in time and met (and in some cases exceeded) the architect’s specification.

It may seem counterintuitive to be talking about sound absorption for a concert venue. A library, yes. But an arena which, as part of its remit to play host to more than 140 events per year, is expected to accommodate rock concerts?

There are two key areas for consideration when it comes to concert acoustics. The first is sound quality, the second is the issue of dangerous levels of sound. Although there are many electrical innovations that can assist in both these areas, the physical acoustics of a performance space are critical. An excess of reflected sound (in layman’s terms, ‘echo’) can measurably reduce the quality of a performance, particularly during classical recitals. In fact, it is not unknown for certain conductors to refuse to play certain venues simply because they do not feel the acoustics complement the piece they are to play. Johann Sebastian Bach composed for a particular church, Saint Thomas in Leipzig, due to its low reverberation. Hope Bagenal, the senior acoustic consultant of the Royal Festival Hall described this as “the most important single fact in the history of music because it leads directly to the St Matthew Passion and the B Minor Mass.”

With regard to the second issue, that of dangerous noise, the maximum ‘safe’ level for continued exposure to noise is around 85dB. On July 15, 2009, during a live performance, the band Kiss achieved a sound pressure level of 136dB, a full 51dB above the accepted maximum. At this level, immediate and permanent hearing damage can be sustained. Not to be outdone, on December 13, 2011 the Foo Fighters concert in New Zealand was recorded on the GNS Science Research Institute’s seismograph, a device normally used for measuring earthquakes and volcanic eruptions. Even the audience at an event can be dangerously noisy. The crowd at CenturyLink Field in Seattle during a Seahawks’ game against the New Orleans Saints achieved a noise level of 137.6dB, without the aid of amplifiers!

Again, technology (and personal liability waivers) provide some solutions, but effective sound absorption materials play a vital role, particularly, as is the case with SuperPhon, when it comes to absorbing those dangerous frequencies around 2000Hz, to which the human ear is especially vulnerable. To give you an idea of how dangerous these higher frequencies can be, for a sound at 50Hz to sound as loud as the same sound at 2000Hz, it would have to be somewhere in the region of 50dB more intense.

Although time had been the issue that had prompted Veitchi Interiors to seek out a new sound absorption material, construction schedules being what they are, it was no longer an issue by the time SuperPhon had been identified as a potential solution. However, CMS Danskin’s fast-track production schedule wasn’t the only quality attracting Veitchi Interiors to SuperPhon. A full 5mm thinner than the originally specified product, SuperPhon was also more cost-effective, enabling Veitchi to value engineer their contribution to this major project.
