  • LA-1410, LA-1440, LA-4440 Integral Average Sound Level Meter (Noise Meter) - No. 1
LA-1410, LA-1440, LA-4440 Integral Average Sound Level Meter (Noise Meter) - No. 2

JIS C 1509-1:2005 compliant
100dB wide linearity range
Simultaneously measures and displays seven noise indicators, including the time-averaged sound level.
Easily perform long-distance noise measurements using a dedicated coaxial cable.

Sound level meters have become an indispensable measurement tool in addressing environmental problems such as traffic noise and ambient noise, which directly affect our daily lives. Furthermore, in many manufacturing industries, including the automotive and consumer electronics industries, more advanced methods such as noise frequency analysis are being adopted in addition to noise measurement, in order to reduce noise from products and design desirable sounds. The needs for sound level meters are also diversifying, and there is a growing demand for support for various applications in combination with recorders, PCs, etc., such as data collection through automatic measurement, long-term measurement, and simultaneous measurement of multiple points remotely.
The newly developed LA Integrative Average Sound Level Meters, models LA-1410/LA-1440 (Class 2, standard sound level meter) and LA-4440 (Class 1, precision sound level meter), comply with JIS C 1509-1:2005 and the Measurement Law (application pending). With a wide linearity range of 100dB, they simultaneously measure and display seven noise indices (Lp, Leq, LE, Lmax, Lmin, Lpk, LN), including time-averaged sound level (Leq), in response to a wide range of sound intensity fluctuations without switching level ranges. Furthermore, the microphone and main unit of the sound level meter can be separated, allowing for long-distance extension with a dedicated coaxial cable. With a curved body that minimizes the effects of sound reflection and an easy-to-read, intuitive operation menu, the new LA Integrative Average Sound Level Meters (Sound Level Meters) offer improved functionality and a more user-friendly interface than ever before. In addition, the LA-1440 and LA-4440 sound level meters (noise meters) allow for quick and easy data transfer to a PC via RS-232C or USB using dedicated free software, or enable remote operation and control of the sound meter from a PC.
