Acoustic Curtains

We design the Acoustic Curtains to provide a degree of sound absorption within the space in which they are used. Noise levels can be typically reduced by as much as 20 dB(A) with a properly designed curtain enclosure Often used in performing arts spaces they not only provide a variable acoustic environment for different applications but control excessive reverberation in halls with very reflective surfaces. All material is chemically treated to create a DFR (Durably Flame Retardant) fabric that will withstand a number of dry cleanings. This meets the requirements of BS5867: Part 2: B which is the British Standard for flame retardant fabrics used for the manufacture of curtains. The degree of sound absorption depends on the weight of the fabric used, the depth between the curtain and the wall and the degree of pleating.

MRI RF SHEILDING

The quality of an MRI image is based upon two things: MRI system technology and RF shielding. A good MRI system will generate a quality image, whereas a good RF shield will protect that image. These two components represent a major investment in time, money and ultimately a commitment to the patient. MRI systems are distinguished in various ways. An open bore versus a closed bore or a 3T versus a 1.5T or smaller magnetic field are just two such examples. Because RF shields are not all alike they, too, are similarly distinguished. Copper or aluminum versus galvanized or steel; self supporting versus gluestaple to parent walls; RF shielding protects the quality of the image created from your MRI system. If you take care to select your MRI system, you should also take care in selecting your RF shield.

Noise Mapping

A noise map is normally generated using computer software that calculates noiselevels from input data such as traffic flows and topography (e.g. ground levels) Computer modeling is used rather than noise measurement as measurement wouldbe prohibitively expensive and it would be technically difficult to isolate differentsources of noise (e.g. that from road, rail, aircraft or industry). Noise maps are normally contour maps showing areas of differing levels of noiseThey can be maps of individual noise sources i.e. road traffic, railway traffic, aircraftin flight or industry. However, all the sources can be combined into one map to givean overall picture of the noise climate.

Noise Mapping

A noise map is normally generated using computer software that calculates noiselevels from input data such as traffic flows and topography (e.g. ground levels) Computer modeling is used rather than noise measurement as measurement wouldbe prohibitively expensive and it would be technically difficult to isolate differentsources of noise (e.g. that from road, rail, aircraft or industry). Noise maps are normally contour maps showing areas of differing levels of noiseThey can be maps of individual noise sources i.e. road traffic, railway traffic, aircraftin flight or industry. However, all the sources can be combined into one map to givean overall picture of the noise climate.

ENVIORNMENTAL NOISE MONITORING & MEASUREMENTS

Our range of noise monitoring solutions is very comprehensive. Based on our customer's inputs and demands we have designed instrumentation aimed at providing the solutions you need, regardless of whether you're in need of just a light-weight, portable, semi-permanent construction site monitoring system or complete systems for airport noise monitoring. The choices are numerous and so are our solutions as well - not to make things complicated, but to ensure that you get what you need, and not what we may think that you need! With this article we would like to introduce you to our range of environmental noise monitoring solutions. As you will see, flexibility is a keyword here - by combining the various elements available there will be solutions for virtually every noise monitoring application!The outdoor microphone units have been designed for permanent installations in the field, such as airport noise monitoring or industrial noise monitoring systems. A typical outdoor microphone system of this type includes anti-bird spikes, a windscreen and a rain cover, all of which are integral parts of the acoustic unidirectional characteristics offered by the system. The rain cover contains an electrostatic actuator enabling a precise in situ calibration at 1000Hz from the internal sine wave generator. Optionally, the complete frequency response may be calibrated using an external generator. A special adaptor allows acoustic calibration. The microphone diaphragm and housing are made of stainless steel to withstand pollution and corrosion.
