Our sound level meters range from the most practical SLM for routine inspections (type 2) to ultra sophisticated SLMs for high precision sound measurement (type 1). CESVA sound level meters are ideal for the control of environmental noise, noisy activities, urban and road traffic, machines (compressors, pumps, etc.), material for sound insulation, preventive medicine, and noise pollution. All CESVA sound level meters comply with current Spanish regulations governing legal metrology.
