Application example of abnormal noise inspection device: Abnormal noise inspection of air conditioning compressors.

We will introduce a case where automatic inspection was made possible by applying an abnormal sound inspection device!

Our "Noise Inspection Device" utilizes an inspection algorithm based on the Maharano Vista Guchi method to automatically and quantitatively inspect the quality of sound and vibration. We would like to introduce a case where the "Noise Inspection Device" was applied to the noise inspection of air conditioning compressors. Traditionally, the presence of abnormal sounds and vibrations was determined by the auditory and tactile senses of the operator. In this case, simultaneous inspection of sound and vibration was achieved using a microphone and an accelerometer. [Case Study] ■ Challenge - Previously, there was variability in judgment due to inspection relying on the auditory and tactile senses of the operator. ■ Application Results - By using DSVI-MB, simultaneous inspection of sound and vibration was achieved with a microphone and an accelerometer. *For more details, please refer to the PDF document or feel free to contact us.

Application examples of abnormal sound inspection devices: Abnormal sound inspection of speakers.

We will introduce a case where automatic inspection was made possible by applying an abnormal sound inspection device!

Our "Abnormal Sound Inspection Device" utilizes an inspection algorithm based on the Maharano Vista Guchi method to automatically and quantitatively inspect the quality of sound and vibrations. Here, we introduce a case where the "Abnormal Sound Inspection Device" was applied to the inspection of abnormal sounds in speakers. Traditionally, the presence of abnormal sounds was determined by the auditory perception of the operator. In this case, automatic inspection was achieved by playing inspection sound sources from the abnormal sound inspection device to a wireless speaker. [Case Study] ■ Challenge - Traditionally, there was variability in determination due to inspection based on the operator's auditory perception. ■ Application Results - By using DSVI-MA, automatic detection of abnormal sounds was achieved using a microphone or accelerometer. *For more details, please refer to the PDF document or feel free to contact us.

New Feature of the Abnormal Sound Inspection Device: Noise Cancelling Function

Introducing the new feature "Noise Cancelling" of the abnormal sound inspection device DSVI-MB!

Our "Abnormal Noise Inspection Device" utilizes an inspection algorithm based on the Maharano Vista Guchi method, allowing for automatic and quantitative inspection of sound and vibration quality. We have recently added a noise-canceling feature to the multi-channel version of the abnormal noise inspection device, "DSVI-MB," using multiple accelerometers and microphones. Previously, depending on the inspection environment, operational sounds from surrounding equipment, noise, and vibrations from conveyors could interfere as noise, making accurate inspections difficult. By using the new noise-canceling feature, we can eliminate sudden and constant noise, enabling accurate and stable inspections. *For more details, please refer to the PDF document or feel free to contact us.*

Abnormal Sound Inspection Device

[Production Equipment] We offer two types of inspections: self-driving inspections and automatic inspections! We will check for abnormal noises inside the vehicle.

The "Noise Inspection Device" is suitable for vehicle assembly lines. It inspects interior noise during actual driving conditions using uneven surfaces installed on a drum roller. There are two types of inspection: one is manual inspection by driving, and the other is automatic inspection by rotating the drum roller with a motor. 【Specifications】 ■ Machine Size: Depth 6400mm × Width 4000mm × Height 2200mm ■ Allowable Axle Weight: 1700kgf for both front and rear wheels ■ Wheelbase Compatibility Range: 2400mm to 3200mm ■ Tread Compatibility Range: 1400mm to 1750mm ■ Maximum Test Speed: MAX 35km/h ■ Road Surface Patterns: Rope road, cobblestone road, undulating road *For more details, please refer to the PDF document or feel free to contact us.

Abnormal Sound Inspection Device 'DSVI-MA/MB' *Case studies are being presented.

Automate and quantify sound and vibration inspection. Replace auditory testing with simple settings. Achieve accurate inspections by eliminating disturbances with noise-canceling features!

The "DSVI-MA/MB" is an abnormal noise inspection device that automatically determines the quality of sound and vibration using an inspection algorithm based on the Mahalanobis-Taguchi method (MT method). By replacing the inspection of sound and vibration, which relied on human senses, with this device, quantitative automatic inspection is achieved. Inspection criteria can be easily created from 40 good product data points, and an immediate improvement in the accuracy and efficiency of abnormal noise inspection can be expected after implementation. The "DSVI-MB" supports up to 4 channels of input. It can determine quality from sensors located in multiple areas. Simultaneous inspection of sound and vibration, as well as vibration inspection in three axial directions, is possible. Additionally, the noise-canceling function removes disturbances such as sudden noise and constant noise, enabling accurate and stable inspections. ★ A collection of case studies is currently being offered. Please refer to the basic information section for details. 【Features】 ■ Easy creation of inspection criteria, ready for immediate use ■ Space-saving design equipped with all necessary functions for inspection ■ Frequency analysis can be performed on-site at the time of measurement ■ Mounting fixtures for acceleration sensors are also available (optional) * You can view the catalog and case studies via "PDF Download." Please feel free to contact us for inquiries.
