NOISE

What is the problem with 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 - it can range from sounds appearing muffled to total deafness. Permanent ‘tinnitus’ or ringing in the ears can be caused as well.

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.

Acoustic Enclosure

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.

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.

Sound Absorption Data

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.

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.
