June 5, 2006 Hearing Protective Device Test Report Number Q1040A Revision 0 Joseph Tokarz. 131 Helman Date of Sample Receipt: 5/28/06 Ashland, OR 97520 Date of Sample Test: 5/29/06-6/5/06 Attenuation measurements have been performed according to the American National Standards Institute (ANSI) Specifications, ANSI S3.19-1974, using the experimenter-fit protocol, on the Tokarz Joe’s Earplugs insert-type hearing protector (test ID Q1040A). The specified threshold measurement data were obtained using ten normal-hearing listeners, six male and four female. These listeners were selected from a standby group of about 35 volunteers, mostly graduate students, who regularly serve as listeners for measurements of this kind. The measurements were made in a room designed for this purpose. All acoustic characteristics of the room meet the requirements outlined in ANSI S3.19-1974. The ambient noise levels in this room are below the limits specified in ANSI S3.19-1974, and open ear thresholds are used on a continuing basis to monitor the background noise levels. An automatic recording attenuator was used to record both open and occluded ear thresholds. Each of ten subjects was tested three times at each of nine test frequencies. The attached Tables show grand mean attenuation values in decibels (dB) for each test signal along with group attenuation values. Standard deviations (S.D.) for the 30 different attenuation determinations for each test signal are also given. The results presented in this report pertain to the samples tested only. Michael & Associates is accredited by the National Institute of Standards and Technology (NIST) National Laboratory Accreditation Program (NVLAP) for tests performed according to ANSI S3.19-1974, ANSI S12.6-1997(R2002) and AUS S1270:2002. These accreditation criteria encompass the requirements of international standards ISO 9002:1994 (ANSI / ASQC Q92-1987) and IS0 / IEC Guide 17025. This report may only be reproduced or transmitted electronically in its’ entirety. This report shall not be used to claim product endorsement by NIST, NVLAP or by any agency of the U.S. Government. All measurement equipment are calibrated with instrumentation traceable to the NIST. Use these laboratory-derived attenuation data for comparison purposes only. The amount of protection afforded in field use is often significantly lower depending on how the protectors are fitted and worn. ______________________________ _______________________ Kevin Michael, Ph.D. Date President 246 Woodland Drive State College, PA 16803 814-234-7042 phone 814-235-1381 fax Email: Kevin@michaelassociates.com URL: www.michaelassociates.com |

NRR 22 is the Lab Certified test results for my soft blue ear plugs. There is no higher NRR and any
claims to the contrary are false. No high density materials have been added to my formula, by any
other company, to achieve higher NRR test results.
