5. Measured Noise Levels
The following table presents the measured noise levels from the unattended noise survey. Any
periods of inclement weather or extraneous noise were omitted from the measured data prior to
determining the results.

5.2    Attended Monitoring
Acoustic Works attended the site on 25th May 2023 at 1:55pm to determine potential noise impacts
associated from the surrounding commercial premises. During the site visit, a collection of
condensers was audible. Measurements were taken at a location representative of the cumulative
noise from the mechanical plant. Noise measurements are detailed below.

                                      Table 2: Attended noise measurement results.
