tube. Usually it is required some adjustment to a lower detection limit for Indoor Air Quality work. Direct Reading Meter( DRM); this device estimates air concentration through several detection values. Some go through chemicals( e. g. CO2 levels), chemical groups or broad pollutant categories( e. g. all respiratory particles which are done using scattered light). Detecting the above will bounds and lessens the time developed for improved IAQ.
Detector tube kit; this device usually includes a hand pump which draws an identified volume of air through a chemically treated tube planned to react with specific air pollutants. The length and depth of the color stain within the tube relates to chemical concentration( e. g. Acidity).
Personal Monitoring Devices( PMD); also referred to as dosimeters are worn or carried by individuals and are usually used to measure individual’ s contact to specific chemicals. There are two types of PMDs; one which do not carry pumps and they are called passive monitors and other which does include pumps and are called active monitors; such devices are used in research currently. There is a big possibility that such devices may be useful in IAQ examination for public and commercial areas ad buildings( Jacobs et al. 2007).
Many more devices can and will be found in the market which will help to detect IAQ very much effectively and efficiently. What makes people have access for such devices more than others or selectively choose Device A over Device B? The following criteria are the main by which professionals and people choose.

Indoor Noise Noise pollution is not less in its affect than other kinds which affect the indoor environment comfort. Noise can be really harmful when it exceeds a certain level; causing physical( especially when it reflects to hearing which is negatively affected and directly correlated to noise and heavy volume disturbances caused by many factors) and physiological health problems. Factors contributing and causing noisy indoor environments usually is a result of residential buildings, surrounding neighborhoods, roads and rails system if any and most importantly it is from HVAC system and mechanical systems( if not installed or maintained probably) in buildings which frame inhabitants every time and anywhere( Sherman 2004; Sherman and Walker 2009).
Thus, what is environmental noise? It is that noise which comes from any source other than an industrial workplace; it is also called community, domestic, or residential noise. This type of noise mostly comes from traffic, includes road and air traffic, and construction sites and equipment operations and all other types of similar work. Environmental noise is also an outcome of neighborhoods, diners, events, car parks and many much more.
