After conducting measurements our company is able to study<\/a> and treat <\/a> any problematic situation.<\/p>\n
Environmental Noise Measurements<\/h4>\n
Environmental noise measurements usually aim to record outdoor noise produced from noisy plants (building mechanical equipment, industrial facilities), road traffic, railway traffic or even airport sources.<\/p>\n

<\/a><\/p>\nThe purpose of environmental noise measurements is usually to compare their results with the allowed limits. The plant noise limits are defined in PD 1180\/11 while traffic noise limits are defined in Greek MR ministerial regulation 211773.<\/p>\n
Acoustic Science performs environmental noise measurements using certified and calibrated high-precision equipment (Class 1 – Type I Sound Level Meters with frequency analysis and data logging). After conducting measurements our company is able to study<\/a> and treat<\/a> any problematic situation.<\/p>\n
Sound Insulation Measurements<\/h4>\n
Sound insulation measurements aim to determine the Sound Reduction Index or Sound Level Difference between two existing enclosures. The purpose is usually to compare an existing condition with the requirement of the Greek Building Regulation or other special building specifications.

<\/a><\/p>\nRoom Acoustics Measurements<\/h4>\n
The measurements of room acoustic properties are conducted by recording the room reverberation and other parameters that express the quality of sound in an enclosure with high standards (theatre, auditorium, conference room, call center e.t.c.). The purpose is usually to compare the results with the acoustics requirements of international bibliography and good practice.<\/p>\n

The measured quantities are analyzed using special software so that conclusions concerning the enclosure’s properties and its declination from optimum acoustic conditions can derive.<\/p>\n
After conducting measurements our company is able to study<\/a> and treat<\/a> any problematic situation.<\/p>\n
Work Vibrations Measurements<\/h4>\n
Work vibrations measurements are conducted in order to record the level of vibrations that machinery operators receive in their hands and body. The measurements aim to compare the vibration levels with applicable legislated limits (PD 176\/2005 and 2002\/44\/EU).<\/p>\n

Machine – Building – Ship vibration measurements<\/h4>\n
Machine – building – ship vibration measurements are usually conducted for precautionary maintenance or fault diagnosis. Building vibration measurements are conducted in structures with strict standards concerning vibration levels (old – preserved buildings, museums, laboratories or residences near railroads, etc). Ship vibration measurements are conducted in order to certify comfort conditions according to international standards.<\/p>\n

Fitness Center Noise Measurements<\/h4>\n
Fitness center noise measurements are conducted in order to issue the certificate of non-disturbance, as required for the authorization of fitness centers in Greece. Measurements are realized inside the fitness center and at the neighboring properties (if the fitness center is detached, then the measurements are conducted on the boundary of the fitness center property) recording the necessary data to judge the disturbance or non-disturbance.<\/p>\n
