Did you know that to be considered officially valid acoustic tests shoould be undertaken by an entity certified by IPAC (Instituto Português de Acreditação)?

LogAcústica collaborates with IPAC (Instituto Português de Acreditação) certified laboratories depending on the location of your building so as to minimize the cost of the acoustic compliance ensuring the best quality/price ratio in the market. 

Acoustic testing typically undertaken for acoustic compliance are:

– Airborne sound insulation

– Impact sound insulation

– Reverberation time

– Plant noise ​

The updated version of the following standards, or parts of these standards, will be used in each compliance case:

• NP ISO 1996: Description, measurement and assessment of environmental noise.

• NP EN ISO 140-4: Measurement of sound insulation in buildings and of building elements – Part 4: Field measurements of airborne sound insulation between rooms.

• NP EN ISO 140-5: Measurement of sound insulation in buildings and of building elements – Part 5: Field measurements of airborne sound insulation of facade elementes and facades.

• NP EN ISO 140-7: Measurement of sound insulation in buildings and of building elements – Part 7: Field measurements of impact sound insulation of floors.

• EN ISO 140-14: Measurement of sound insulation in buildings and of building elements – Part 14: Guidelines for special situations in the field.

• NP EN ISO 717-1: Rating of sound insulation in buildings ad of building elements. Parte 1: Airborne sound insulation.

• NP EN ISO 717-2: Rating of sound insulation in buildings ad of building elements. Parte 2: Impact sound insulation.

• EN ISO 3382-1: Measurement of room acoustic parameters – Part 1: Performance spaces.

• EN ISO 3382-2: Measurement of room acoustic parameters – Part 2: Reverberation time in ordinary rooms.

• NP EN ISO 16032: Measurement of sound pressure level from service equipment in buildings. Engineering method.

 

Did you know that the presentation of an acoustic test report does not suffice to determine if a building complies with the legal acoustic requirements?

In fact, a test report is a document that includes the description and results of the acoustic testing, carried out in accordance with the applicable standards, undertaken by an entity that complies with the requirements of nº 33.º and 34.º of the "Regulament Geral do Ruído", approved by Decreto-Lei n.º 9/2007 of January 17.

However, it is not part of the acoustic test report to compare the measured results with the legal requiremets and thus assess compliance of the tested partitions.

On the other hand, sampling needs to be considered, i.e. the number of test carried out, which should ensure an adequate representation of the different types of built partitions as well as the acoustic criteria of the several parts that form the legal acoustic compliance.

To this end, a recognised Specialist Acoustic Engineer (Engenheiro Especialista em Acústica) should be employed, who should define which tests to carry out and will produce a technical advice report in which the legal acoustic compliance assessment is included.

Example of the results of an acoustic test report:

Did you know that in several instances a Specialist Acoustic Engineeer (Engenheiro Especialista em Acústica) must undertake the Technical Advice?

At LogAcústica you will always have the Technical Advice undertaken by a Specialist Acoustic Engineer, recognised by the Ordem dos Engenheiros, without this being an extra cost for you, just an additional insurance of quality.

The Technical Advice is the document that assesses compliance with the legal requirements, to be undertaken by a qualified technician in accordance with nº 2 of the 3º clause of the Decreto-Lei 96/2008, of June 9 (Regulamento dos Requisitos Acústicos dos Edifícios), aproved by the Decreto-Lei n.º 129/2002 of May 11.
