Low Frequency Sound Level Meter NA-17 Rental
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.

basic information
**Features** ○ Has a flat frequency characteristic "LSPL" (Low frequency sound pressure level) to obtain physical evaluation values. ○ Has a frequency characteristic "LSL" (Low frequency sound level) for sensory correction. ○ Contains a flat characteristic "SPL" (sound pressure level) from 1Hz to 1,000Hz for convenience in corresponding to sound pressure levels. ○ The dynamic characteristics of the meter are the same as the SLOW of a sound level meter, with an indication of -4±2dB for a signal with a duration of 0.5 seconds. ○ In addition to indicating the actual value, it has a maximum value hold and peak value indication function. ● For more details, please contact us.
