Abstracts
This research study aims to measure the volume of the. Separate the audio frequency and volume maps to indicate the location of the equipment, which is the source for analysis, make noise, and how to prevent and resolve. Machines that make noise. Tools used in this research include a measurement of sound brand DUO version by 01DB measure sound coverage Steam Ground floor building floor area power plants South Bangkok, 2 in the form of average sound level Leq 3 min number of 225 points to measured data to map sound levels (Noise Contour Map).
The study found that the average sound level Leq values are in the range between 81.3 – 93.3 de saben El maximum sound level (Lmax) 94.4 DB(a) and the sound level is low (Lmin) 80.0 DB(a) sound level value areas by highest average Air Compressor Pump is a machine when a separate sound measurement frequency, found that the average sound pressure level (Leq) is in the range of 88.4 – 92.6 DB(a) and are in the range of frequencies.
63 – 4000 Hz, by volume, in the 2000 Hz frequency range.
Key words: combined heat power plants, maps, building Steam volume.
