Sound measurement
Measurement of working environment in a factory
The sound pressure level from factory can be
monitored by using the sound level meters. Separate the
microphone from main unit of LA-1440 max. 100m and set
it at the boundary line between factory and private
house.
Separate the microphone from main unit of LA-1440 and
set it at the boundary line between factory and private
house which is required noise monitoring. Then place the
main unit of LA-1440 in the office away from the
microphone 200 m.
The LA-1410 is cost-effective integrating sound level
meter with simple operation. It measures and displays
the sound which is generated from machine during
operation at every one second over again.
The LA-1410
has a function to measure the maximum value and
time-average sound level (equivalent continuous sound
level, Leq) of time duration from start to stop.
This example shows how to measure the time-average
sound level (equivalent continuous sound level, Leq)
which is generated from machine during operation.
Environmental measurement
This example shows how to measure and monitor the
sound level by using continuous measurement function of
LA-1440. For example, measure the maximum value and
time-average sound level (equivalent continuous sound
level, Leq) continuously for an hour. This continuous
measurement function allows long time measurement at
fixed point outdoors.
This example shows how to measure and monitor the
sound level by continuous measurement function of
LA-4440. For example, measure the maximum value and
time-average sound level (equivalent continuous sound
level, Leq) continuously for an hour. This continuous
measurement function allows long time measurement at
fixed point outdoors.
This example shows how to measure the NC (Noise
Criteria) value as the environmental evaluation item of
the background noise in the state of air-conditioned and
calm space such as indoor, hall and hospital.
When you have to think about the setting of sound
insulating wall or partition with absorptive material in
order to cut off the noise from machine etc. in a
factory, you need to study the frequency distribution of
sound characteristics and choose the suitable and
effective material for blocking out the noise according
to its frequency characteristics.
This example shows how to measure and analyze the
sound characteristics of the environmental noise which
is generated from a factory or hall etc. by using the
sound level meter and FFT Analyzer.
In this example, the object which generates the sound can be recorded and replayed as a video corresponding to its data of sound level synchronously. It allows the visual checking of its causes when there is the sudden fluctuation in sound level at automatic sound measurement.
This example shows how to analyze tire squeal sound which occurs in sliding velocity of a tire. Record the squeal sound to an SD memory card in the LA-5560 up to 15 minutes per measurement. By using the OS-2720 FFT analysis pack, it can play back the recorded data on a PC with sound function or perform FFT analysis.
This example shows how to inspect component parts of a railroad vehicle by using the LA-3260 High functional sound level meter. Hammer the component parts and measure the hammering sound while checking it through headphones
The loudness level is used as a value index for evaluation of improvement effect before and after countermeasures for noise reduction.
We can easily perform FFT analysis of the noise which is generated from home appliances or the like by sound level meter.
We can easily perform FFT analysis of the noise which is generated from home appliances or the like by sound level meter. FFT, 1/1· 1/3 octave, and level trend analyses are performed by using the sound level meter as well as frequency analyzer.
In this example, the sound level meter with comparator function makes determination of the operating noise of the product on the production line which is generated from the products such as OA equipment and home appliance.
In this example, the small operated sound from electrical parts such as a small motor is measured by sound level meter with high sensitivity microphone in order to analyze and make OK/NG determination.
In this example, you can perform FFT analysis of noise from operated product and make OK/NG determination with the operating noise level at the specified frequency bands in the analyzed data on the final testing of production line.
In this example, ｔracking analysis of sound and vibration from rotationing machine is performed. The sound level generated from rotationg machine is changed with respect to the number of rotations. The changing of sound level due to rotational changes is analyzed with precision sound level meter etc..
