If you’re in the market for a sound level meter, HK Calibration Technologies is your one-stop shop that has everything you could possibly need. Capable of accurately measuring the levels of various types of sound, our digital sound level meters are ideal for various purposes, including environmental and industrial noise pollution studies. 

Sound level meters are essential tools for accurately measuring noise levels across different environments. From monitoring workplace safety and ensuring compliance with regulations to analyzing community or environmental sound, these instruments provide reliable insights into how noise impacts daily life and business operations.

Why Use a Sound Level Meter?

Noise pollution and workplace sound exposure are growing concerns in today’s fast-paced world. Excessive noise can cause long-term hearing damage, reduce productivity, and even lead to regulatory penalties. A sound level meter helps you:

  • Stay compliant with occupational health and safety standards.
  • Monitor noise levels in factories, workshops, or construction sites.
  • Ensure safe environments for employees and the public.
  • Evaluate sound quality in studios, classrooms, or performance spaces.

Frequently Asked Questions

HK Calibrations offers a range of digital sound level meters, class 1 and class 2 noise meters, and data-logging decibel meters. Models vary by accuracy, frequency weighting (A/C/Z), and measurement range suitable for environmental, industrial, and workplace applications.

 A sound level meter uses a microphone to detect pressure variations caused by sound waves. It then converts these signals into electrical values and displays them in decibels (dB), typically using A-weighting to reflect the sensitivity of human hearing.

 Noise levels are calculated using logarithmic scales. The meter measures the sound pressure level (SPL) in decibels (dB), factoring in time and frequency weighting. For multiple sources, logarithmic addition is used rather than simple arithmetic summation due to the nature of sound intensity.

 A noise decibel monitor is a device that continuously measures and records sound levels in decibels (dB). It’s used in workplaces, public venues, and industrial environments to ensure that noise stays within legal or safety limits, helping meet occupational health and environmental compliance.

To check noise levels, use a calibrated sound level meter. Turn it on, select the appropriate weighting (usually A-weighting), and hold it at ear height, pointing toward the noise source. The display will show the current sound pressure level in decibels (dB).

Accuracy depends on the meter's class. Class 1 sound level meters offer high precision (±1 dB or better) and are used for environmental assessments. Class 2 meters are slightly less accurate (±1.5 dB) but suitable for general-purpose and workplace noise measurements.

Sound level meters should be calibrated at least once a year or more frequently for legal compliance or intensive use. Pre- and post-use field calibrations using an acoustic calibrator are also recommended for daily accuracy checks.
