The Process Of Carrying Out A Noise Assessment At A Work Place

By Tiffany Gill


Many people do not know that certain noise level at a work site can eventually lead to hearing problems or deafness to people working in that environment. There have been regulations designed by different states to help reduce the number of cases of workplace deafness. Apart from the regulations, certain tools have been devised to assess the level of discordance at a work place and advocate for reduction measures. One such example is the noise assessment tool.

Persons at the workplace can be chosen to conduct this assessment such as a health and safety representative, a supervisor, an employee or even a manager. The first step will be to identify the source of the problem. The reason why persons from the organization are used is because at this level not much technical expertise is required.

The evaluator thus prepares a worksheet that contains questions that will be asked during the process. Methods that may be used to collect the data include checklists, observations, and interviews among other methods. The worksheet starts with inquiring about the hazard source. In many work places it may be from a compressor, a photocopier, machines, conveyor, radio, power tools and many other numerous sources.

The next thing that will need to be determined is the persons most affected by the hazard. This should be indicated in the worksheet and also a map of the work area that will be provided for the process. After this is established next will be measuring the level of loudness of the sound. A discordance meter is used in this process. If it shows that the level is below 75 db, this is an acceptable level. However, any level above this causes harm to workers.

After finding out that the sound levels at the workplace are harmful, an evaluator needs to see the measures that the company has taken to minimize this. There are numerous measures that can be taken but most places utilize hearing protection control units. In some situations, these measures do work but in some scenarios they do not.

In situations where the protection measures do not work, assessment continues. Here a more complex instrument is used for data collection. This instrument has additional features and the evaluator needs to be trained on how to properly use it to ensure proper collection and interpretation of data. The people at the work place can still be involved in this process.

If after the above step sound cannot be minimized, then this calls for professional help. Complex measurements will need to be carried out by an external consultant. The measurements taken here require use of more sophisticated instruments which the consultant has been trained to use. There should be a team formed by people working at the particular workplace to work closely with the consultant.

Once the professional has finished carrying out the noise assessment, he comes up with a report. This report contains all information people at the work area ought to know concerning the hazard; its effects are proposed measures to rectify the problem. It will be up to the organization to implement the report in order to protect its workers.
