A8 52.9 44.9
A9 62.9 Not measured
A10 51.0 Not measured
The highest noise levels were observed in the Ihovbor-Evboeka community
(wet season) and sampling site A4 (dry season), where the noise levels were
recorded as 62.9 and 58.5 dB (A) respectively. These are considered high for the
semi-rural context of the Project site, and it is expected that this is as a result of
the short-term construction noise from the activities at the NIPP site as well as
weather conditions (heavy rain during the wet season) during sampling.
Due to the ongoing construction activities close to the site during the baseline
sampling fieldwork, it was not possible to measure the baseline noise
conditions. The noise modeling and the impact assessment assumes noise
levels of below 45 dB(A) LAeq, 9hr consistent with the semi-rural environment of
the area around the Project site (Chapter 7). In addition, the NIPP EIA provides
results of ambient noise levels (Table 4.7) measured as part of their specialist
investigations..
