Voice for Walcha commissioned an acoustical engineering company to execute a Technical Review of the noise report done by Vestas, which forms part of the EIS. The review identifies significant errors in how the Developer mismanaged compliance with standards, regulation, assumptions and general scientific skill on assessments. The report is highly technical.
Winterbourne the Developer says, that no property owner other than those who have agreed to have turbines installed on their land, will experience sound levels higher than what is allowed by NSW Planning and therefore the project can proceed.This is incorrect. We believe that because of the mistakes made by the Developer the actual sound levels may be as much as 14 decibels (dB) higher than predicted.
From a scientific view point every 10dB increase in sound level is heard as a doubling in “loudness”.
There is a very high likelihood that hundreds of properties, currently considered as unaffected by sound, will fall outside the allowable legislated limits and a new turbine layout will need to be proposed.
The EIS is intended to describe as accurately as possible, the before and after effects of these turbines, so all those affected can understand exactly what to expect.
The current EIS fails to do this, with respect to sound. There is no doubt that the sound study must be done again without mistakes.
Please join us by submitting an objection to the EIS with this being at least one of the reasons. We need to get these objections in by Jan 23rd.
