Since a silent apparatus hardly exists, noise protection apparatus engineering is especially important in times of growing environmental concerns. The rising consciousness of safety and health ensures that adequate sound protection apparatus and electrical engineering acoustics and electrical machines engineering for acoustic insulation will take on greater importance. A further reason for mandatory improvement of the acoustic apparatus is the apparatus protection noise regulations, which are used in 57 different machine and apparatus types.

Improve air duct insulation and air conditioner acoustic insulation

Due to their technology and construction, many apparatuses produce a substantial sound level, making apparatus sound protection indispensable. Even the sound level of household appliances is often disturbingly high without effective apparatus acoustic insulation. The ventilation or air conditioner is also often too loud. The air conditioning system must have appropriate sound deadening, in order to counteract noise disturbance and annoying noise by the generator. Air duct insulation should also be provided. Acoustic foams from aixFOAM offer numerous possibilities of subsequently integrating soundproofing in an air conditioning sound protection system, or providing ventilating system sound deadening.

Besides inward protection, the ventilating system must also be secured against sound transmission. The limit values for air duct soundproofing depend on the land development area and the environment in which the plant is operated. Much higher requirements apply to the sound protection for generator in populated areas than in industrial ones. Ventilation system sound insulation should be given a high priority when planning new construction, or in the forefront of reconstruction.

It must be ensured that sound doesn't enter the building through the air duct. Air duct sound dampening will counteract sound transmission between individual rooms of a house. If the ventilating system is located in closed rooms, the wall, floors, and ceilings must be sufficiently quietened to secure ventilating system sound protection against noises penetrating outward.

Soundproofing in energy production

Renewable energy is becoming increasingly important. They are environmentally friendly, and are available almost without limit. However, constructing factories for this purpose entails a number of problems. The noise of wind power stations cannot be underestimated. The same can be said of heat pumps. Due to their proximity to residential buildings, thermal power stations sound protection is often integrated, so their emitted noise doesn't disturb residents.

A wind turbine produces sound in several places. Although the rotor blade noise caused by wind turbulence cannot be quieted, wind turbine noise and noise-producing technical components can be outwardly isolated with professional sound absorbers like aixFOAM membrane absorbers or acoustic heavy foil.

If heat pump sound insulation is necessary, aixFOAM membrane absorbers which are designed to absorb low frequencies and made of special heavy foam, are the right solution. This acoustic foam also has good impact sound insulation values, thereby providing suitable heat pump noise protection.

Thermal power station sound has very low frequency. Since this is highly disturbing to residential areas, chp sound deadening must be integrated to ensure sound insulation in the generator. For optimal chp sound protection, for example, massive engine casings, chp sound insulation in the interior, constructing passive thermal power station sound deadening, or integrating an active sound deadening according to the "antiphase" principle.

Medical Devices Soundproofing

The medical field occupies a very important place regarding soundproofing for electronic apparatuses. The devices it employs tend to vibrate, due to their size and the large-surfaced plastic coverings their size makes necessary. In order to counteract these vibrations, and improve the pneumatic devices insulation and medical devices soundproofing, it is necessary to increase the area density of the machine housing.

aixFOAM developed a special acoustic heavy foil for this purpose, which is very flexible and easily handled. To reduce airborne noise, membrane absorbers can also be used here. These are not only washable, thanks to a protective plastic film, but also protected against splashing water and dirt, and thus ideally suited for the higher hygiene requirements of hospitals and other medical facilities.

Soundproofing for electrical machinery construction and noise protection for construction equipment - Electric motor acoustics

Suitable soundproofing for electrical appliances is often already integrated nowadays by the equipment manufacturer to combat noise levels in domestic appliances. However, an older electric motor can still make acoustic noise, and require improving the acoustics in the electro-technology. Since aixFOAM sound absorbers can be made in almost any form using most modern CNC technology, they offer flexible possibilities for improving acoustics with machines driven by electric motors, electric motor sound deadening.

Since the aforementioned Noise Protection Act also applies to construction equipment, an appropriate soundproofing electronics should also be ensured in this area. Meanwhile, many manufacturers offer low-noise construction equipment, with which cumbersomely upgrading the soundproofing is a thing of the past. If the sound emissions of older construction equipment exceed the permitted sound level, one can use quiet construction noise abatement through effective measures. aixFOAM acoustic foams are characterised not only by their unusually good sound-absorbing characteristics, but also offer easy handling and innumerable variation options, and thus suitable solutions for almost any acoustic problem.
