Dear Mr. Johnson,

C~t

This letter is in reference to R03-9 dated February 20, 2003. I am the Standards

Director for the Acoustical Society ofAmerica. Recently, I received a copy ofthis

document and was surprised to see that much of the text ofproposed Sections

910.106 and 910.107 was taken almost word for word from ANSI Si 2.9 Part 3-1998

(R2003). Perhaps it was not noticed that this is copyrighted material.

The only revenue to support Standards development in the United States for

Standards of this type is sales ofthe Standard. Thus, no permission can be given for

you to use the text from ANSI S12.9 Part 3 in this fashion. We would be pleased if

you would reference the methods ofANSI Si2.9 Part 3. In any event, we hereby

require that you remove all copyrighted material taken from ANSI Si2.9 Part 3 from

your proposed rule. Further, we request that you ask all recipients of the R03-9

Proposed Rule dated February 20, 2003—Proposal for Public Comment to destroy

any and all copies of these two proposed sections; Section 910.106 and Section

910.107. Finally, please send us copies of your correspondence and the revised text

of the document demonstrating that these actions have been taken.

Thank you for your prompt response and attention to this matter.

Very sincerely,

G~~L
