IEC 61672-1:2002 Certified Sound Analyzer FAQs

Question 1

1. What is the KingPo KP-AW20 Sound Analyzer?

Accepted Answer

It is a professional Class 1 (Type 1) precision sound level analyzer certified to IEC 61672-1:2002, optimized for accurate environmental noise measurements, including applications compliant with ISO 3744:2010 (acoustics — determination of sound power levels of noise sources using sound pressure).

Question 2

2. What accuracy class does this sound analyzer meet?

Accepted Answer

It is a Type 1 / Class 1 instrument per IEC 61672-1:2002, which provides the highest level of accuracy and is suitable for laboratory-grade, legal, environmental, and compliance testing (tighter tolerances than Class 2 meters).

Question 3

3. What standards does this device comply with?

Accepted Answer

IEC 61672-1:2002 (electroacoustics — sound level meters — specifications) Designed to support accurate measurements in environments following ISO 3744:2010 (sound power determination using sound pressure in reverberant or free-field conditions).

Question 4

4. What is it mainly used for?

Accepted Answer

It is ideal for precise noise mapping, environmental noise assessments, sound power level determination (ISO 3744), occupational noise monitoring, product noise compliance testing, research, and regulatory reporting where high-accuracy Class 1 performance is required.

Question 5

5. Does it support integrating-averaging and time-weighted measurements?

Accepted Answer

Yes. As a sound analyzer compliant with IEC 61672-1, it supports common Class 1 functions such as time-weighted sound levels (e.g., LAeq, LAF, LAS), integrating-averaging sound levels (Leq), statistical levels, and other relevant acoustic parameters needed for environmental and ISO 3744-related testing.

Question 6

6. Is this device suitable for outdoor or environmental use?

Accepted Answer

It is specifically highlighted for ISO 3744:2010 environment accurate measurements, indicating suitability for controlled acoustic environments (e.g., free-field or reverberant test rooms) and general environmental noise applications when used with appropriate accessories (windscreen, etc.).

Question 7

7. What is the minimum order quantity (MOQ) and pricing?

Accepted Answer

MOQ: 1 unit Price: To be quoted (contact KingPo for current quotation and detailed quotation).

Question 8

8. How long is the delivery period?

Accepted Answer

Standard delivery is approximately 15 days after order confirmation and payment arrangement.

Question 9

9. What certifications does the manufacturer hold?

Accepted Answer

KingPo holds ISO 9001 and CE certifications for quality management and product compliance.

Question 10

10. How can I get more detailed technical specifications (frequency range, dynamic range, microphone type, etc.)?

Accepted Answer

Detailed technical specifications (e.g., exact frequency weighting, linear operating range, self-noise, etc.) are available upon request. Please contact KingPo Technology directly via the website or sales team for the full datasheet, calibration information, or customization options.

Question 11

11. Does the device require periodic calibration?

Accepted Answer

Yes, like all precision Class 1 sound level meters under IEC 61672, it should be periodically calibrated (recommended annually or per local regulations) using a compatible acoustic calibrator to maintain accuracy.
