In June 1998, NIOSH researchers recognized the necessity of rebuilding the NIOSH Hearing Protector Device Testing Laboratory. Several design requirements influenced the software development and hardware selection. First, the hardware must be commercially available and easily operated from personal computers that use the Microsoft Windows operating system. Second, software must have the flexibility to support not only the demands of a research laboratory and field studies but also be configurable such that a commercial laboratory could use the software for production testing of protectors. Finally, the complete package must ensure the use of standard operating procedures for the purpose of achieving and maintaining NVLAP certification for the ANSI S12.6 and S3.19 standards for the measurement of real-ear attenuation at threshold. The total system has been operational since May 2002 and has been installed in three laboratories to date. This paper will present how these competing needs were addressed in the development of the NIOSH HPD Lab software.
