Data Storage and Access
One*dB for Windows categorizes sound exposure data into seven types:
This category contains information pertaining to a particular plant or building located at the specific site. If multiple plants exist at a site, those plants will be identified here.
Department/Section Group Information
This information contains a list of all the various departments or work groups found at the specific site. It stores the department or group number, description, and notes taken during the sound survey.
Job Code and Job Classification Information
This category houses the master list of employee job classifications found at the specific site. Job codes identify a particular job classification and are used to indicate the type of work an employee is able to perform.
Risk Group Information
This type of information provides details concerning all of the sound exposure risk groups at a specific site. It stores information pertaining to the job functions, the representative TWA exposure level, and the number of employees at risk.
Job Function Profile Information
This category contains all of the sound exposure profiles found at a specific site. Each record contains the detailed exposure analysis of a distinct job function including the job tasks and their corresponding sound levels.
Activity Sample Information
This category stores all information collected for an individual sample measurement. Each sound sample represents the activity or task of a particular job function and form the building blocks for a sound exposure profile. For example, data such as Activity Description, Lavg, Lmin, Lmax, Lpeak, Noise Source, and Bay Location are included in this grouping.
Noise Source Information
This category of information identifies all of the noise sources found at a particular site. Noise sources are used to classify sound sample data into primary noise types.
The user will notice that there is some overlap between these categories of data, that is, certain parameters are found in more than one category grouping. This is especially true with organizational information such as Department Number and Job Classification. This allows for interaction between the various groups of data so that information can be shared. For example, while viewing a profile, the user can access a table of all the risk groups of a particular job classification group. Many "links" such as this exist between each of the seven major groupings of data and greatly enhances usability.
