Audits of inspection companies in the field of noise pollution prevention
A regional authority delegates the tasks of inspection and control in the field of noise pollution to a series of private entities. To verify that all the entities and their qualified personnel remain in compliance with the technical requirements for qualifying as providers of these services, they must be subjected to periodical follow-up audits, which on this occasion have been entrusted to ITeC.
Assessment of dry floating flooring kit with ceramic tiles
As an alternative to traditional ceramic flooring, a manufacturer has developed a system akin to floating laminated floors, supplying the tile with an elastomeric base mat that provides an interlocking mechanism between tiles and also insulation to impact noise. The differences with the classic system have required the elaboration of a specific technical evaluation protocol, according to the European criteria for construction products without harmonized standards.
Lightweight dry floor slab with improved insulation of impact noises
Assessment of the acoustic insulation performance (both aerial noise and impact noise) of a dry-mounted lightweight floor slab with improvement recommendations regarding the choice of materials for its horizontal surfaces. It also includes a cost analysis.
Impact in the construction costs of the new acoustic requirements of the Spanish Building Code
An apartment building project has been selected as a representative sample of the current demand and ITeC has calculated the execution costs using the typical building techniques prior to the entry into force of the acoustic chapter (DB-HR) of the Spanish Building Code, and also with the techniques that should be adopted to satisfy the new noise insulation requirements.
European requirements guide to assess natural cork insulation
Development of a European guide of requirements for assessing products for thermal and acoustic insulation manufactured with granulated natural cork mixed with organic binders and shaped as uncoated boards. The protocol obtained is fairly similar to that for chemical insulation, and checks the insulating properties of the cork boards and also their mechanical, geometric and fire performance.
Thermal and acoustic study of a ventilated facade
Assessment of the thermal and acoustic insulation of the precast housing units as designed by the manufacturer, quantifying the degree of compliance with the current standards. The units feature a double wall enclosure with a mineral insulation filling, with two choices of external finish: ceramic panels or cement particle boards.
ACUST/ITEC software for acoustic analysis
Program that calculates the reverberation time of a room, considering the designer’s choice of materials to be used. It applies the Sabine, Eyring and Millington formulas for the 6 most common frequencies and, in order to assess whether the results are admissible, it compares them with the optimal reverberation times that it suggests according to the type of use for the room.
Manual of practical control systems for built objects
Guide for the measurement of the parameters specified by the building codes in the fields of acoustics, artificial lighting, electricity supply, thermal transfer, temperature, relative humidity and air renewal. With a list of the necessary equipment for the control program.
