DO YOU NEED A CUSTOM DESIGN?

Using acoustic prediction software, we calculate the insulation deficit of each construction system (walls, doors, windows, ceilings, roofs, floors, etc.). After this first approach, we specify the correct material and its quantity within the best cost-benefit for the customer in order to solve their noise problem as required by the municipality.

ACOUSTIC MEDIATION – REPORT AND EXPERT EVALUATION

Measurement of sound pressure levels, according to the standards established by ABNT (NBR 10.151: 2019).Acoustic recordings will be made at frequencies between 20 Hz and 20,000 Hz in 1/3 octaves, in dB(A) response circuits.

GEOMETRICAL ACOUSTICS

It will be developed in computer theoretical models, allowing us to evaluate the geometry of the place, detecting possible echoes, and to indicate the best location of the acoustic materials. By defining the location of the source and receiver at various locations in the room, we will be able to observe the path of the sound rays and where they reflect, as well as the time and intensity of each reflected ray in relation to the direct ray (Level vs. Direct).

ENVIRONMENTAL LICENSING AND NOISE ZONING

Environmental responsibility is increasingly incorporated into the fundamental policies of large companies. In a modern view, environmental management models are based on the principle of continuous improvement, where the objective is the ability to control the environmental effects of its own activities, products and services, being able to walk towards the systematic reduction of current environmental impacts.

REVERBERATION TIME

The Reverberation Time (Tr) of a room is the indicator par excellence of its acoustic behavior. It is determined by the volume of the room and the sound absorption coefficients of the cladding materials and equipment installed inside the room. The Tr optimal values, for the six main octave bands, of 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz, according to the volume of the room and the intended use.

ACOUSTIC CONDITIONING

With three-dimensional acoustic modeling carried out in acoustic prediction software, we will evaluate all sound waves, their paths, intensities and reflections up to the fifth order. For each project, more than 10,000 sound rays will be evaluated with different placements of sound sources and receivers, allowing for optimized geometrical acoustics with excellent sound in different parts of the room.
Nabinger calculates and provides all acoustic descriptors according to international recommendations, such as: REVERBERATION TIME, RAY TRACING, WORD INTELLIGIBILITY %AL CONS, STI, CLARITY C5, C50, C100, D/R RATIO, HOT SPOT, CRITICAL DISTANCE, LOUNDNESS, etc…

ACOUSTIC INSULATION PROJECT

Through the diagnosis of construction systems, the acoustic insulation deficit is calculated by frequency in 1/3 octaves Hz (Hertz), and with international acoustic software, projects are carried out to correct this deficit in order to comply with municipal and federal law (NBR 10.151 and NBR 10.152) on noise.
Objective 1: comply noise with municipal and federal laws (NBR 10.151)
Objective 2: provide acoustic comfort to the user (NBR 10.152)
