Noise measurements

World-class experts in the field of sound and vibration measurements discuss everything there is to know about noise measurement.

The most important thing to know about measuring sound measurement is that it’s the transmission of energy through vibrating air particles, which is a form of vibration. As a result, sound measurements are concerned with changes in local air pressure caused by noise energy.

You can study the following topics in this section of the course:

ANSI/ASA S1.4-2014/Part 1 / IEC 61672:1-2013 sound level meters and noise sampling
IEC 61652 noise dosimeters and noise exposure
IEC 61672 noise monitoring terminals and environmental noise monitoring

Noise at the International Space Station

Noise at the International Space Station Challenges and Innovations Excessive noise can harm both spacecraft systems and astronaut well-being. High decibel levels may mask critical alarms and interfere with sensitive instruments. Meanwhile, astronauts exposed to loud or constant noise can experience hearing loss, stress, and reduced cognitive performance. Ensuring a safe acoustic environment is therefore […]

How to choose the best noise dosimeter

How to choose the best noise dosimeter for workplace noise monitoring Noise dosimeters are essential tools for monitoring sound exposure in the workplace. Choosing the best dosimeter involves understanding the difference between a personal sound dosimeter and other sound level meters, adhering to international standards like IEC 61252 and ANSI S1.25-1991, and evaluating specific device features.

Sound Wave

Sound wave definition, characteristics, and use in acoustics A sound wave is a mechanical disturbance that propagates through a medium such as air, water, or solids, carrying energy and information via oscillations of pressure and particle displacement. It encompasses a broad range of frequencies, including those audible to humans (20 Hz to 20 kHz) as […]

Sound frequency

Sound Frequency Sound Frequency: a comprehensive understanding of its nature, analysis methods, and applications is essential for acoustics, impacting human perception, health, and various technological fields. What is the meaning of frequency in sound? In acoustics, the frequency of sound refers to the number of vibrations or cycles that occur in a sound wave per […]

How to choose a noise monitoring station

How to choose a noise monitoring station:

SV 307A: Integrated noise monitoring station with lifetime microphone warranty and patented remote microphone sensitivity check mechanism. Recommended for continuous monitoring of traffic and industrial noise.
SV 200A: Integrated 4G noise monitoring station designed to detect sound directionality. Recommended for aviation noise monitoring , thanks to its ability to identify dominant noise sources.
SV 279 PRO: Class 1 noise monitoring station based on SVAN 979, in a waterproof case. Designed for short- and medium-term measurements in harsh weather conditions.
SV 303: Smart city monitoring, a station dedicated to multi-point noise monitoring in cities. Integrates with sensors that monitor the urban environment, ideal for smart city applications.
Match SvanNET subscriptions to your monitoring station: enables remote monitoring, real-time data storage and analysis. Cloud integration allows easy access to measurement results from anywhere. Provides support for notifications when established noise thresholds are exceeded.
Select additional accessories for the monitoring station:
- Tripods or mounting brackets for stable installation at the target site.
- Wind shields to protect the microphone in harsh weather conditions.
- PC software for detailed analysis of measurement data.
- Consider power options:
- Permanent power supply for long-term monitoring.
- Rechargeable batteries or solar panels for locations without access to the power grid.
- Ensure that the station and its accessories meet local standards for noise monitoring.
- Regularly service and calibrate the station, to ensure accuracy of measurements.
