The frequency range can be selected from 1 to 50 Hz and 1 to 1,000 Hz.
The Low Frequency Sound Level Meter NA-17 is a level meter that measures low frequency sounds, referred to as low frequency noise and low frequency air vibrations. It is based on the concept proposed by Dr. Yasuo Tokita of the Kobayashi Institute of Physical Science, which considers the frequency range of 1 to 50 Hz as the low frequency sound domain. It has a flat frequency response for indicating the physical characteristics within this range and a frequency response for obtaining evaluations corresponding to psychological effects. 【Features】 ○ Level handling is done using 20log10P/P0, the same as in noise meters. ○ The frequency range for low frequency sound is from 1 Hz to 50 Hz.
