Applications

Applications of Svantek’s sound and vibration level meters include a diverse range of fields, including industrial, occupational, and environmental. Svantek meters are designed to meet British requirements for assessing airborne, impact, and facade sound insulation in buildings, as well as for speech transmission measurements. In industrial settings, Svantek meters are used for machine vibration as well as occupational noise assessment. In environmental applications, Svantek meters are utilized for noise and vibration monitoring systems to monitor the UK’s transportation routes (road, rail, and air traffic) as well as urban noise in cities.

Building acoustics

Building acoustics as described in BS EN ISO 16283 takes into consideration airborne and impact and facade sound insulation in buildings.

machine vibration

Measuring machine vibrations

Machine Vibration Measurements typically based on analysis of the vibration frequency, displacement, velocity, and acceleration.

noise measurement

Sound measurements

Sound is a sensation perceived by the human ear resulting from rapid fluctuations in air pressure. These fluctuations are usually created by some vibrating object which sets up longitudinal wave motion in the air. Sound measurements provide definite quantities which describe and rate sounds.

building vibration

Building and ground vibrations

Generally, there are two methods of building vibration measurements: one that uses PPV method with the FFT or zero crossing for dominant frequency analysis and second that analyses vibrations in 1/3 octave bands. Both methods use different criteria for building damage and they might interpret the same vibration event differently.

environmental noise

Environmental noise

The ISO 1996 standard series and BS 4142:2014 describe the assessment of environmental noise. The methods and procedures are intended to be applicable to noise from various sources, individually or in combination, that contributes to the total exposure at a site.

whole body vibration

Whole-body vibration

ISO 2631-1 defines methods of whole-body vibration measurements in the frequency range from 0.5 Hz to 80 Hz for health, comfort and perception and from 0.1 Hz to 0.5 Hz for motion sickness. The vibration evaluation according to this part of ISO 2631 is based on measurements of the weighted root-mean-square (RMS) vibration acceleration.

hand arm vibration

Hand-arm Vibration

Hand-arm vibration is usually complex and may be the result of the construction of the device, structural defects or its usage. During human contact with the surface of the vibrating machine, mechanical vibrations are transmitted directly to the human body, affecting the individual tissues or even the whole body.

occupational noise

Occupational noise measurements

The occupational noise measurement is based on assessment of daily noise exposure level (LEX, 8h) defined by ISO 1999. The LEX,8h is basically a 8-hours extrapolation of LAeq measured over the working hours. The Directive set up limits for LEX, 8h: 87 dBA as the daily limit, 85 dBA as the upper action value and 80 dBA as the lower action.
