Sound Level Meter TYPE 6236
Precision Sound Level Meter TYPE 6238

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 6236/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.

World first!! “0-dB function”

By employing the original DSP technology, which eliminates the self-noise of the microphone with preamplifier, the lower limit of measurement has been drastically extended to lower than 0 dB-SPL. Linearity range, extended to 100 dB in the usual state, further expands to that corresponding to the measurement range 0～80dB(A) by holding the 0-dB function in ON position.

It enables to measure ultra-low sound pressure level, so displaying its greatest power as in the quietness measurement of, or tone quality evaluation of, various silent-type IT/OA equipments, as well as in the measurement of air-conditioning noise or sound isolation in a concert hall with ambient noise below NC-20.

※Technology relating to “0-dB function” is the fruit of joint research work with Shizuoka University.

Embedded high precision microphone

TYPE 7052NR TYPE 7146NR

TYPE 6236/TYPE 6238 is equipped with high precision electret condenser microphone(TYPE 7052NR/TYPE 7146NR) which ACO is most proud of.
The measurement frequency range covers entire audible frequencies,TYPE6236:20Hz～20kHz,TYPE6238:5Hz～20kHz.

 

ACO Microphone is made as one with highly anti-shock capability

TYPE 7052NR TYPE 7146NR

"Microphone has a image of breakable object needing frequent replacement"

Such an image is broken down by ACO microphone of highly anti-shock capability,developed through lengthy research and development work.
