Inquiry (采购产品): Baseline dB testing I need to perform a baseline noise test for a client on a commercial lot close to residential housing. Is there an industry standard in PA for testing? I dont know much about this at all. What type of equipment is needed, what costs are we looking at, and a time duration on length of the testing? Please respond by email first. I will be driving past Philadelphia tomorrow morning, then back again in the afternoon, perhaps I could just stop by?
