NOISE


Effects of noise?

Sounds and noise are an important part of everyday life. In small amounts they are harmless, but if they are too loud they can cause problems. Hearing damage caused by noise is permanent and incurable. Exposure to prolonged or excessive noise has been shown to cause a range of health problems ranging from stress, poor concentration, productivity losses in the workplace, and communication difficulties and fatigue from lack of sleep, to more serious issues such as cardiovascular disease, cognitive impairment, tinnitus and hearing loss. What does the law say?

The Noise at Work Regulations 1989 say what you and your employer must do. It is important that you and your employer co-operate - it is your hearing that will be damaged if the danger is not controlled.


Acoustic Enclosure


The control of noise in industry is becoming very important. Increased

worker compensation claims involving hearing damage, and the advent

of ever-increasing legislative; safety and economic requirements make a

noise reduction program mandatory for many industries. Additionally, the

government Provincial, or Local ordinances have been enacted to further

protect the communities from unwanted ‘Industrial ’noise as it migrates

offsite. To meet these specific noise reduction requirements, Ecotone

manufactures and supply a complete line of acoustically designed

panels, which can be quickly and easily assembled to provide complete

or as desired, partial enclosures for any noisy equipment. Ecotone panels

are designed to provide optimum noise control through the time proven

method of sound transmission loss and sound absorption, using our

proprietary internal arrangements and key specified materials to meet

or exceed your requirements. Our unique panel internal

arrangements are specifically designed for each application and are

sized to meet your requirements.

Additionally, enclosures can be designed with doors, windows, access

panels and removable panels, floors. Doors are equipped with

heavy-duty hardware and with seals to prevent further noise leakage.

Window panels are framed and gasket sealed as specified. If constant

access to the equipment is needed, removable panels will be incorporated

in the enclosure design. All-important ventilation of the enclosure is also

incorporated into the design based upon your requirements. Specialty

paints, finishes and metal types are also available upon request.

Ecotone acoustic enclosures are designed to control noise generated from any machine, the noise reduction should be as per client requirement or as per pollution board norms/ISO 14001 norms for noise pollution

As per CPCB / ISO 14401 norms noise

should not be more than 75 dB(A) at one meter from enclosure surface

All acoustic enclosure comes with air ventilation system to avoid any heating inside the enclosure which might affect machine performance.

Ecotone acoustic

enclosures



We have provided a following range of Acoustic Enclosures, to our clients:

• Glass Crusher Acoustic Enclosure • MS Sheet Cutting Machine Enclosure • Noise Test Chamber • Engine Test Cell • Wind Turbine Noise Control • AC Noise Testing Booth • Machine Noise Control Barrier • Wire Winding Machine Enclosure • Machine Enclosure with Vertical Lift doors • Compressor Enclosure • Anechoic Chamber

Range of noise Enclosures



Each enclosure is designed and manufactured to suit or be a heavy integrated housing. Additional features include lifting beams, lighting, fire and gas detection & protection systems.

We also offer the drop over design which has the advantage of low installation time, quick access to the noise generating machines for major maintenance. Acoustic Enclosures are dismountable type, we can dismantle easily and re-erect at alternative site.

All our enclosures are designed to allow the maximum aspiration and cooling airflow required to make sure machine does not overheat. Weather louvers, acoustic louvers, splitter and baffles are provided to suppress the noise where required.

Acoustic enclosures will be as varied as the customer's requirements. The enclosure outer walls generally consist of

1.6-2mm thickness of CRCA steel sheeting outside, and inner surface is GI perforated sheet filled with tissue paper laminated rock wool pads.

Mitigation recommendations included:

• attenuate radiated compressor noise by erecting a sound curtain barrier wall,

• control reflected noise from the ceiling by adding a roof to the sound curtain wall,

• reduce reflected noise by adding acoustical absorption to the adjacent concrete wall and ceiling surfaces,

• construct a dedicated room to enclose the two compressors from concrete block or stud and gypsum board, and

• relocate nearby employees to a location further away from the compressors.

Sound Transmission Loss

Sound Absorption Data

Ecotone offers a proven engineered solution for air compressor noise. A sound curtain enclosure constructed of Sound Curtain Panels and support frame custom designed and fabricated to meet your application requirements.

• Sound reduction of 12 – 18 dBA • Silenced passive or forced air ventilation available • Easy access to the equipment • Enclosure easily installed and moved with equipment

Air blower noise enclosure

Ecotone has designed Blower Enclosures for removable acoustic steel sound enclosures for Blower Enclosures. Our blower enclosures are designed for your specification, whether they are needed for 85 dBA (decibels) of lower, something that can be a concern in a quiet community property line. We can also make sure that other high sound reduction levels are met as well.

The blower enclosures have been measured to be 60-80% quieter in all aspects of the installation process, including during and after the equipment install. This is done by our designed and manufactured Blower Enclosure system. Some features that are included are the frame system, silenced air intake, modular acoustic steel panels and exhaust fans.

Many different clients have happily utilized our blower enclosures for various purposes. All the features with the Ecotone Blower Enclosures create an easy maintenance and durability in a long period.

Please call us today to discuss all your Blower Enclosure needs and we will have an experienced engineer or consultant be happy to answer any questions you may have.



CNC Machine noise enclosure

CNC punch presses are capable of producing high levels of noise, depending on the type of material and operation they are performing. An older machine, for instance a 30-ton, 40-station mechanical press, can expose an operator at the control panel to 95 dB(A) during a typical punching cycle on 3 mm steel. Improvements in design have made newer machines generally quieter than older ones, although according to manufacturers’ figures the noisiest operations can still result in noise levels above 100 dB(A) at the operating position.

Ecotone is able to reduce CNC machine noise by 25-40 dBA using a noise suppression treatment.

Sources of noise from CNC punch presses: Punch presses generate noise from a number of sources, including:

• tool impact; • the driving mechanism; • hydraulic pumps; • sheet manipulation; • the clamping mechanism; • transfer and collection of punched components; and vibrating machine panels
