First Step : A baseline noise survey
Next, getting a reference:
Next, in order to establish the key noise sources and to anticipate the likely noise levels arising from the proposed development, iAcoustics attended another local Nikafit premises during a busy evening class in Kilcoole which was similar in scale, setup and occupancy. A representative internal noise level during a typical class was established at this reference location.
Noise sensitive Neighbours
iAcoustics then undertook a detailed site survey and desktop analysis of the subject site in order to determine the likely levels of sound insulation afforded by the existing building envelope to ensure no breakout of gym noise. The subject site shares a common boundary with the Whale Theatre in Greystones; background noise levels in theatre settings need to be very low, sudden noises can negatively impact moments of suspense during theatrical performances. iAcoustics needed to carry out a detailed spectral analysis based on the anticipated noise levels inside the development, the sound insulation of the separating walls, and the required levels inside the theatre. We are able to determine that noises generated within the gymnasium would be inaudible to individuals situated in the theatre.
A clever approach to amplified music:
An obvious concern with gymnasiums is the impact of amplified music. We made it clear in our report that consideration must be given to the fact that Nikafit offer personal training on a one-to-one or small group basis. Loud, intrusive music would hinder the instructors’ ability to deliver clear instructions to the group, negatively impacting speech intelligibility; it would be simply incompatible with the Nikafit business model. We observed this at the reference premises in Kilcoole. The gym also utilises a highly effective sound system which allows speakers around the premises to be individually controlled, meaning the music could be played only in areas where it was needed, and reduced or turned off completely in areas where it is not, therefore minimising noise generation.
