High-Performance Sound Level Meter

LA-7000シリーズ

The LA-7000 series sound level meter features a large color LCD touch panel, significantly improving operation and allowing for easy and intuitive measurement.
The LA-7000 series not only measures and calculates noise levels, but also allows you to "measure while listening to sound" during the measurement process. By listening to the sound, you can check the condition of the object being measured, locate the sound source, and confirm that the recording was successful. This enables safe and reliable measurements in measurement environments where failure is not an option.
Furthermore, by equipping optional features, it evolves beyond just a sound level meter (noise meter) into a sound analyzer, frequency analyzer, and sound recorder*. (*Optional)
The LA-7000 series sound level meter allows for noise measurement, sound recording, frequency analysis, and source detection of abnormal noises, significantly improving the efficiency of measurement work.
Furthermore, by combining the data saved with the LA-7000 series with our diverse range of analysis software, it becomes possible to perform waveform analysis, sound quality evaluation, fluctuating sound analysis, and sound frequency simulation.

Inquiry

<Trend screen: Displays the trend waveform of MAIN or SUB. Only the selected value is shown. (MAIN or SUB)
*Trend display is based on a combination of instantaneous values or calculated values.

List > Screen: Displays all calculated values (L _p, L _eq, L _E, L _max, L _min, L _peak, L _N) during measurement for the selected MAIN or SUB.
*To select, tap on the MAIN or SUB display; it will change to bold (indicating selection).

RTA1/1 mode

This is one of the frequency analysis modes, displaying the data divided into octave bands. The vertical axis represents sound pressure level (loudness), and the horizontal axis represents frequency (pitch). You can see at a glance which pitches are loudest. You can also overlay and compare the memory data of RTA1/1 with the MAIN data.

Filter1/1 mode

By listening to sounds filtered through an octave band filter, you can isolate and hear only the sounds that are bothering you, even in noisy environments.
It helps to pinpoint the source of unusual noises by holding the microphone up to them.
Additionally, you can compare the sound pressure levels of Allpass (entire frequency range) and Bandpass (specific band).

Measurement range	Normal range (Wide range is not supported)
Memory mode	Manual, Auto, Logging, Record* (When LA-0704* is installed)

This can be used when you want to correct for ambient noise at a site during noise measurement.

What is background noise correction?
The sound pressure level measured while the equipment being measured is operating is a combined value of the sound emitted from the equipment and the background noise. Subtracting the effect of the background noise from this measurement to calculate the radiated sound pressure level of the equipment is called background noise correction.

Ambient noise correction function RTA mode

Points to note
When measuring ambient noise levels, it is important to obtain a sufficiently stable value.
In the frequency band, if the ambient noise data is larger than the signal, correction cannot be performed and the data will not be displayed.

*The overlay function and ambient noise reduction function can also be used in RTA1/3.

Convenient feature 1

The recommended calibrator to be used can be registered in the sound level meter.
Registration items: Model of the calibrator used, calibration level value, serial number

Convenient Features 2

Once calibration mode is completed by selecting OK, the calibration data is automatically saved to the internal memory (up to approximately 100 times). This calibration history data can be exported to an SD card (in .CSV format).
Items saved: (Calibration value, adjustment VR position, acoustic calibrator/internal reference signal used, calibration date and time)
*You need to register and select the calibration device you will be using.

Noise level evaluations can sometimes differ from human perception. In such cases, sound quality evaluations, such as loudness ratings, can be very effective.
Loudness is a useful tool for evaluating the perceived loudness of sound.
Sharpness is useful for identifying metallic, high-pitched, unpleasant sound components.

The CI value* is a value that takes into account time-averaged sound level and sharpness. It is simple and effective for applications such as ambient noise and machine noise (dental drills). (Further research is being conducted on its application scope.)
The LA-0708A's sound quality evaluation function is designed for stationary sounds. For non-stationary sound loudness evaluation, please use the sound quality evaluation software from the Oscope series.

Normal Range

* This product cannot be attached to the LA-7200 (Class 2).
* CI (Comfort Index) is one of the sound evaluation metrics developed by Professor Sonoko Kuwano.* CI is the sum of the "sharpness value" and "1/10 of the A-weighted time-averaged sound level." There are correlation examples with environmental noise and mechanical noise, and it is considered an effective measure for evaluating unpleasant sounds. The scope of application is still being investigated, so please use it as a reference value.

Detailed analysis using analysis mode

By importing data (in WAV format) recorded with the LA-7000 series (+LA-0704) into O-Solution, you can play back the sound, perform frequency analysis, and octave analysis on your PC.
Additionally, by using an IIR filter (optional), it is possible to listen to the filtered sound while playing back the recorded audio.

As a signal input source for the DS-5000

Instead of using a microphone, you can input the analog output of the LA-7000 series into the DS-5000 to perform real-time analysis. The LA-7000 series can simultaneously output two signals: one with an acoustic filter (such as A-weighting) and one with a flat (Z-weighting) signal. These can then be analyzed simultaneously by the DS-5000.

Predicting various noise sources in the same field

SoundPLAN noise environmental prediction software

This is acoustic simulation software that predicts and calculates how noise generated from roads, railways, factories, etc., propagates.
Even in areas where various noise sources such as road noise, railway noise, factory noise, large retail stores, construction work, and power substations coexist, complex calculations can be performed without switching software.
