Low Frequency Sound Level Meter "NA-18A" [Rental]

This is a low-frequency sound level meter that enables real-time analysis of 1/3 octave bands while measuring the G characteristic sound pressure level.

It can measure low-frequency sounds (1 to 500 Hz). It can measure low frequencies (1 to 100 Hz) that are difficult for humans to hear (or inaudible). 【Features】 - Equipped with G-weighting frequency characteristics and real-time analysis function for 1/3 octave bands. - Simultaneously measures low-frequency sound pressure levels (1 Hz to 100 Hz), G-weighted sound pressure levels, and 1/3 octave band levels (FLAT). - G-weighted frequency characteristics, RMS detection circuits, and 1/3 octave band filters utilize digital processing via DSP. - Data can be transferred to a computer via serial communication, allowing for editing in spreadsheet software.
