Hi mohammadosamaa7161,  

dB sound pressure levels are unweighted. dBA levels are “A” weighted according to the weighting curves shown below to approximate the way the human ear hears. For example, a 100 dB level at 100 Hz will be perceived to have a loudness equal to only 80 dB at 1000 Hz. Other weighting scales (C and B) are also shown. The dBA scale is based on a child’s hearing and was originally documented based on actual hearing tests to characterize the human ear’s relative response to noise.

Thanks & Regards
Clark Kent

    Hi,

    As this question is from  the database section so the answer should  be connected to that arena, whatever the answer is mention by Mr Clark kent are not striking the section of the database, here user need to ask what is the difference between DB and DBA in the database.

     DB (Database) which is the file format  in windows; here files  store information about the data along with storing the data  in the series of table, table fields, and field data values, Whatever the information is in DB that must be stored in an organized manner according to the data model. DB file can be created using database software like Microsoft Access and  FileMaker Pro. DB files can be exported in .CSV format using these programs.

    MIME:application /msaccess,application/x-msaccess, application/vnd.msaccess, application/vnd-access

    Whereas  DBA define database administrator.DBA is an IT professional responsible for the installation, configuration, upgrading, administration, monitoring, maintenance, and security of database in an organization.Basic role includes the development and design of database strategies,system monitoring and improving database performances and capacity, and planning for future expansion requirements.They also plan co-ordinate and implements security measures to safeguards the database.

    Thanks & Regards
