Earplug-type noise canceler "Airtos ER"

Earplug-type noise canceler "Airtos ER"

Significantly cuts unpleasant high frequencies! You can hear voices clearly, ensuring safety and comfort. These earplugs are breathable, with almost no feeling of stuffiness or pressure.

The "AirToss ER" is an earplug-type noise canceller that reduces only the noise levels, making voices easier to hear. It is useful not only in daily life but also in factories to prevent mistakes and accidents caused by decreased concentration. It allows necessary sounds (voices) to remain while reducing unpleasant noises. It has holes that allow air to pass through, minimizing any sense of pressure or stuffiness. 【Features】 ■ Reduction of discomfort ■ Maintenance of desired sounds (voices) ■ No stuffiness even with long-term use *For more details, please download the PDF or feel free to contact us.

Noise reduction with a single collection microphone 'ANC'

Noise reduction with a single collection microphone 'ANC'

By using a single collection microphone, cost reduction is achieved, there are no discrepancies in microphone performance, and noise reduction accuracy is improved!

Active Noise Canceling (ANC) is a technology that utilizes the ability to synthesize sound by generating a phase-inverted sound that cancels out noise, thereby reducing it. By outputting the canceling sound from a speaker in response to the sound collected by a pickup microphone, noise is reduced. Our company's ANC system is characterized by achieving noise reduction with just a single pickup microphone.

Active Magnetic Field Canceller "AMC-331"

Active Magnetic Field Canceller "AMC-331"

Introduction of a high-performance active magnetic field canceller created by the micro-vibration measurement technology of patented equipment.

The "AMC-331" is a high-performance active magnetic field canceller that protects electron beam application devices from magnetic field fluctuations. By controlling the disturbance magnetic field detected by magnetic field sensors using a combination of a controller and Helmholtz coils, it suppresses the effects of disturbance magnetic fields. It helps improve the images of electron microscopes and enhances the processing accuracy of electron beam processing devices. 【Features】 ■ Excellent attenuation performance of up to 40-60 dB ■ Achieves about 1/10 the cost compared to magnetic field measures using shielding ■ Simply fix the coils around the device ■ Design coils according to the target device ■ Control multiple disturbance magnetic fields precisely based on frequency analysis *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Countermeasures for DC Magnetic Field Interference in Scanning Electron Microscopes (SEM)

[Case Study] Countermeasures for DC Magnetic Field Interference in Scanning Electron Microscopes (SEM)

We will introduce a case where a DC fluctuating magnetic field was reduced to less than 1/100 by an active magnetic field canceller!

We will introduce a case study on countermeasures for direct current magnetic field interference in scanning electron microscopes (SEM). For the SEM installed in a demo room within an office building, the magnetic field effects caused by nearby railway lines were reduced using an active magnetic field canceller, improving the environment. The active magnetic field canceller can achieve significant improvement effects simply by installing coils or similar devices around the target equipment. 【Case Overview】 ■ Key Points of the Countermeasure: Significant magnetic field fluctuations occur constantly near direct current railway lines. ■ Cause: Multiple railway lines located near the target building. ■ Countermeasure and Effect: The active magnetic field canceller reduced the direct current fluctuating magnetic field to less than 1/100. *For more details, please refer to the PDF document or feel free to contact us.
