Acoustic measurements and certifications

Acoustic measurement

We are specialists in carrying out measurements in accordance with the following International Standards:

• Environmental sound level measurements (noise measurement): ISO 1996:1,2,3 standards
• Characterization of industrial noise sources: ISO 3744, 3748, 3741 standards, ... engineering methods to determine sound power levels.
• Acoustic insulation tests:
  • ISO 140:3 standard for airborne noise in the test chamber.
  • ISO 140:4 standard for airborne noise between rooms.
  • iSO 140:5 standard for airborne noise from facades and roofs.
  • ISO 140:7 standard for structural noise.
• Verification tests of passive noise control systems :
  • Silencers: ISO 7235:2010, ISO 11691:2010, ISO 11820:1997 standards.
  • Acoustic cabins: ISO 11546-1.2: 2010 standard.
• Measurement of reverberation times:
  • ISO 354 standard for tests in reverberant chambers.
  • ISO 3382 standard for enclosures.
• Vibration measurements: in buildings, in machinery, in facilities (structures, pipes, ducts).

Acoustic certificate

We are specialists in the certification of compliance with regulatory acoustic limits:

• Noise in the environment: RD 1367/07, regional regulations and municipal ordinances on noise and vibration:
  • Analysis of Acoustic Quality Objectives.
  • Analysis of immission levels in exterior and interior spaces.
  • Vibration analysis.
  • Sound insulation levels.
• Noise inside the building: DB HR, and the requirements of the RITE.
• Acoustic certification of buildings in accordance with CTE DB HR: RD 1371/07.
• Verification by means of measurements of the specifications of specific technical conditions in industrial projects (EPCs conditions):
  • Levels inside industrial plants.
  • Levels emitted by noisy equipment and machinery.
  • Acoustic attenuation levels of noise reduction solutions.
  • Acoustic comfort analysis: acoustic comfort curves (NC, ISO, PNC…), reverberation times.
• hecking sound immission levels of roads, railway lines, ports and airports.
• Noise in the workplace : Directive 200/2003, RD 286/06, OSHA standards...
