On-site measurement of environmental noise is strongly expected to have high resolution and real-time analyzing

function on the spot. Moreover, in the field of product development such as car parts electric appliances, etc., it is required to measure and analyze the sound of ultra-low level more accurately, corresponding to the rise of consciousness that the acoustic

characteristics such as silence, tone quality, etc., should be the part of the product, which is deeply related to our human hearing sensation.

The function of TYPE 6238 can be extended quite easily to those such as measurement of various parameters for environmental noise, only by inserting option FFT Analysis Card into the card slot. Also, this equipment is provided with newly developed "0-dB function" for measuring ultra-low sound pressure level, symbolizing the next-generation sound level meter with extremely high resolution and reliability.
