My primary noise concern lies within the ventilation system, making it essential that the hired professional is capable of minimizing this noise to a moderate level, between 50-70 decibels. The successful candidate must be have experience in conducting acoustic assessments, with the appropriate knowledge and tools to produce the desired result.
