Customized Acoustic Solutions

Tailor-made and Efficient Solutions

At HiAcoustic, we understand the importance of providing customized and efficient solutions for the acoustic conditioning of spaces housing generators and industrial equipment. We specialize in offering tailor-made solutions, employing the best products and materials available in the market.

How do they work?
Our team of engineers conducts a detailed evaluation, gathering the technical specifications of the room to be soundproofed. With this information, we design a customized acoustic solution and provide an accurate cost estimate. By considering crucial factors such as room dimensions, airflows required by the equipment, noise exhaust, and the presence of anti-vibration elements, we create solutions tailored to the specific needs of each client.

See 3D
Construction
To address the room dimensions, we install acoustic sandwich panels that cover all walls, including the ceiling. We complement this with the installation of acoustic doors that allow access to the room. These components are manufactured to the highest quality standards, ensuring effective sound absorption and reduction.
Materials
Acoustic sandwich panels use high-quality materials to ensure optimal acoustic absorption. Additionally, we implement rectangular silencers in ventilation openings to control noise without compromising the necessary cooling for the equipment. To attenuate noise from the exhaust, we install radial or axial exhaust silencers, addressing the direct source of noise radiation.
Acoustic Properties
We carefully consider the airflows required by the equipment and use silencers to facilitate air flow and cooling, preventing noise leakage. The strategic installation of anti-vibration elements at key points in the equipment plant and its extremities, such as pipes, helps cancel or minimize the transmission of vibrations, significantly contributing to noise reduction.

Acoustic Enclosures

A comprehensive solution for generator sets

HA-CA acoustic enclosures are specifically designed to specification to house internal combustion engines and, in particular, generator sets.

How do they work?
These enclosures are meticulously designed to confine and transport sound sources, in particular internal combustion engines and especially generator sets. Precise mass and stress calculations are carried out, taking into account structural safety and ensuring optimum acoustic and ventilation performance.

See 3D
Construction
The enclosures comply with transport standards and regulations, and are structurally reinforced to ensure safe transportation. The 80 mm thick acoustic absorption panels are made from perforated galvanised steel sheet metal to maximise absorption. The built-in rectangular silencers are made from galvanised sheet steel and filled with inorganic fibres.
Materials
Perforated and smooth galvanised sheet metal and 80 mm glass wool panels of varying densities are used. These materials guarantee both acoustic protection and the ability to withstand adverse weather conditions.
Acoustic Properties
Noise reduction is achieved through acoustic absorption and adopted geometry. A detailed analysis of the noise source allows for a tailor-made design, and silencers are installed to ensure that the noise level remains within the project limits. The approximate attenuation is specified by frequency.

Tackling High Sound Levels

Tackling High Sound Levels

The HA-SE exhaust silencers are designed to reduce high sound levels, especially those produced by the exhaust gases of power generators, while also mitigating noise from compressors, pumps, turbocharged engines, and generators. They can attenuate sound by 30 dB or 40 dB, depending on the requirements.

How do they work? Exhaust gases enter the expansion-compression chamber; due to these volume changes, attenuation occurs at low frequencies. Subsequently, the absorption silencer is traversed for mid and high frequencies with an inner core.

See 3D
Construction
Manufacturing involves the use of materials such as perforated carbon steel sheet, rock wool, and accessories according to customer specifications. If greater attenuation (more than 40 dB) is needed, a custom exhaust based on the quarter-wave tube can be designed.
Materials
These silencers are made with carbon steel and constructed to withstand temperatures up to 490 °C. If this limit is exceeded, the use of stainless steel would be considered. Noise analysis is conducted to tailor different parts of the exhaust based on flow and sound spectrum.
Acoustic Properties
Acoustic features show attenuation at different frequencies for the 30 dB and 40 dB models. The materials used include carbon steel, perforated sheet metal, and glass wool with different densities and thermal properties.

Acoustic Cabins

Integrated solutions for noise control

The HA/CA-80-DS Acoustic Cabins have been designed with the primary purpose of containing the noise generated by ventilation machines, preventing its spread in the surrounding environment. These cabins have various applications in industrial settings, providing an effective solution to protect workers, sensitive equipment, and reduce noise produced by compressors, fans, and other manufacturing equipment.

How do they work? Its operation is based on its ability to encapsulate and absorb the sound generated by ventilation machines. Its design is oriented to prevent noise from radiating outward, protecting both workers and delicate equipment. Below, key aspects related to the manufacturing, materials, and acoustic features of these devices will be detailed.

See 3D
Construction
The exterior structure of the cabin is entirely constructed with 1 mm thick galvanized steel, providing strength and durability. The interior is coated with 0.8 mm acoustic panels, made with insulating and absorbing materials such as acoustic wool. The support structure consists of 80/80/2 steel structural tubes, ensuring a robust and stable base.
Materials
The use of galvanized steel on the exterior and acoustic panels with insulating materials on the interior contributes to the effective absorption and reduction of sound. The acoustic wool used in the manufacturing of the interior panels plays a crucial role in absorbing and dissipating sound waves, ensuring a quieter working environment.
Acoustic Properties
The ability to block sound is complemented by the presence of air intakes and exhausts equipped with 8 recessed nurse nuts in the acoustic enclosure. These additional features contribute to optimizing acoustic control, offering superior performance in reducing noise generated by compressors, fans, air conditioning systems, and power generators.

Rectangular Silences

Designed for ventilation and air conditioning ducts

HA-R- /200 rectangular silencers are key components for noise control not only in ventilation and air conditioning ducts in generator sets, but also in heating and ventilation units, compressors and combustion engines.

How do they work? These silencers contain acoustic baffles made from inorganic, non-combustible fibres, strategically arranged to achieve specific levels of attenuation. Features such as an aerodynamic front (model A) minimise pressure drop and noise regeneration.

See 3D
Construction
Manufactured to specification from galvanised sheet metal or stainless steel, the baffles are filled with rock wool fibres of varying densities. Accessories, such as angle flanges and METU components, are customised to meet the client's needs.
Materials
Smooth galvanised sheet metal is used for the enclosure and structure of the baffles, together with perforated galvanised sheet metal in cases of high air velocities. The baffles contain glass wool panels of various densities.
Acoustic Properties
Acoustic attenuation is fine-tuned based on a detailed analysis of the sound source, taking into account the frequency range and decibels in each band. Attenuation is determined by insertion loss and the point of immission and is adjusted to one-third-octave bands for tonal sounds or octave bands for broadband sounds. The effectiveness of the silencer is determined by measuring the regenerated noise at high air velocities.

Acoustic Screens

High sound absorption capacity

The HA-PA Acoustic Screens represent an effective solution for attenuating noise radiated at the source by machines and equipment that require increased ventilation and cannot be encapsulated. This innovative approach allows maintaining an adequate ventilation level without compromising noise reduction. A noteworthy feature of these screens is their easy portability and the possibility of uninstalling them for later reinstalling in different locations.

How do they work?
Its on-site performance depends on various factors such as the size and geometry of the screen, the distance to the sound source, the proximity to the location where the screen effect is needed, as well as the presence of nearby partitions such as walls and ceilings. These elements work together to provide optimal acoustic control in industrial environments.
