Abstract
This study focused its efforts on sound power levels and noise reduction of power tools used by workers at both commercial and residential construction sites. The objective was to develop a noise control technology database consisting of power hand tools used in the construction industry with respective sound power levels and workers’ sound exposure level (SEL). The database and specific noise control applications information are made available to the public on a searchable web-site. Data includes a particular tool’s wavfile and time series signatures to be used for future qualitative and quantitative analysis by other acousticians accessing the database. With this information, reasonable assumptions can be made as to the potential occupational noise exposure expected for various occupations, tasks, etc. and as to potential sources of noise within the powered hand tool itself. The database captures tool types, tool models, tool manufacturers, and decibel power level. The database is expandable to include new tools and new manufacturers as the power tool population changes over time. These efforts support the reduction of noise induced hearing loss among construction workers by providing ‘‘buy quiet’’ and ‘‘designed quiet’’ information to power tool buyers and end users.
