Audio Equipment EMC Testing Agency

With the widespread use of audio equipment in households, businesses, and professional fields, the issue of electromagnetic compatibility (EMC) has become an increasing concern. As a professional third-party EMC testing organization, JJR Laboratory in China is committed to providing comprehensive EMC testing services to audio manufacturers and users. We help ensure that products meet market access standards and maintain reliable performance in complex electromagnetic environments.

Definition and Importance of Audio EMC Testing Services

EMC testing services aim to assess the electromagnetic interference (EMI) level and electromagnetic susceptibility (EMS) of audio equipment, ensuring that devices do not interfere with other electronic devices during normal operation while also being resistant to external electromagnetic interference. Through EMC testing, the following can be achieved:

- Compliance with national laws, regulations, and market access requirements.

- Improved product quality and market competitiveness.

- Prevention of customer complaints and potential recall risks arising from EMC issues.

The Necessity of EMC Testing

In today’s electronic environment, electromagnetic interference is ubiquitous. Audio equipment, due to its unique operating principles, can both generate interference and be susceptible to interference from other devices. Therefore, EMC testing is crucial for audio equipment:

- Ensure product compliance: Meet various market regulations and industry standards, such as CE, FCC, and other certifications.

- Enhance user experience: Avoid noise, signal loss, and other issues that could affect sound quality.

- Reduce risk costs: Through early detection and rectification, minimize future repair and compliance costs.

Range and Types of Audio EMC Testing Samples

Our audio EMC testing services cover a wide range of product categories, including but not limited to:

- Home audio systems

- Professional audio equipment (e.g., stage audio, studio audio)

- Bluetooth speakers

- Car audio systems

- Smart speakers

- Multimedia audio systems

Specific Items and Standards for Audio EMC Testing

1. EMI (Electromagnetic Interference) Testing

 - Radiated Emissions: Testing the electromagnetic waves emitted by the audio equipment during operation and their impact on the environment.

 - Conducted Emissions: Testing the electromagnetic interference conducted through the power supply lines of the audio equipment.

 - Testing Standards: EN 55032, fcc part 15, etc.

2. EMS (Electromagnetic Susceptibility) Testing

 - ESD (Electrostatic Discharge Immunity Testing): Assessing the device's ability to withstand electrostatic discharges.

 - EFT (Electrical Fast Transient/Burst Immunity Testing): Simulating transient interference on power or signal lines.

 - SURGE (Surge Immunity Testing): Testing the device's ability to withstand high-voltage surges.

 - RS (Radiated RF Immunity Testing): Evaluating the device's stability in high-frequency electromagnetic fields.

 - CS (Conducted RF Immunity Testing): Simulating interference from RF signals through cables to the device.

 - Magnetic Field Immunity Testing: Assessing the device’s resistance to power frequency magnetic fields.

 - DIP (Voltage Dips and Interruptions Immunity Testing): Testing the device's performance under power grid fluctuations.

 - Testing Standards: EN 55035, IEC 61000-4 series, etc.
