Client: Merlin Entertainment Ltd. Alton Towers Resort
Contract dates: 2016 – 2018

Cahill Design Consultants was contracted by Alton Towers, Staffordshire, to offer acoustic support to their proposed SW8 Roller Coaster, proposed to be located within the Alton Towers Resort.
The proposed roller coaster was a large scale timber coaster with a proposed two barrel rolls, a camel back and the first launch to be constructed on a wooden coaster.
The coaster was proposed to be located centrally within the Alton Towers Resort.
CDC was contracted to ensure that sound impacts from the propose coaster were understood and mitigation incorporated into the design drawings.
A wooden roller coaster has different challenges to a steel coaster in regards to sound, as the sound frequency content is different.
In order to understand the potential impacts, a large amount of research was undertaken including extensive communication with the US based coaster manufacturer.
Extensive sound surveys were undertaken in the vicinity of Alton Towers, in order to understand the existing ambient noise levels around the Resort.
Good levels of communication with the Local Authority were essential in order to establish an appropriate acoustic criteria and input on the survey locations.
Extensive calculations and modelling was undertaken to understand the likely impact of sound from different parts of the coaster track to defined receivers. A number of alterations to the coaster design were proposed in order to minimise the effects of sound. These included a tunnel arrangement on the first drop and barriers strategically located throughout the ride.
