Final Report for £..'ant/Cooperative Agreement Number NAG-I-2140
Dear Mr, Lacks,
Imust first apolo lateness of this report. I appreciate the notice sent by Ms.
Reddic's letter of J 4, 2002, Unfortunately that letter was sent to our old address and
delivered here on iday, 19 April 2002, For the record, please note our new address
above. I believed atyou were notified ofthe address change last year, but apparently
this did net occur, was not recorded. Arso for the record, as was reported in January
2001, Avdl Brenig ,tired on 31 December 2000. Isucceeded her as Standards
Manager of the Ac )ustical Society of America on 1Januanj 2001.
We would like to tl NASA for itssupport of the ASA Standards program over the
three-year grant p_rlod. Standards development is a painstakingly slow process but
over the three-yea_ I:_,eriodof this grant, we are pleased to report that much has been
accomplished. ]1]i 8 f
As outlined in the _latement of work dated November 1998, the Acoustical ociety o
America provides 8ecretariats for 4 ANSI Accredited Standards Committees:
$1 Acousti
$2 JlVibration and Shock
$3
$12 Noise.I I
Under these standards committees there are approximately 65 working groups
of which about 35 re active at the time the application to NASA was made. During
the course of the ]fit, the Acoustical Society, with support from NASA, worked to
expedite the devek )merit of the work items inthese committees. The NASA Grant
helped support the lilect and indirect costs associated with the work of these working
groups and the St; _dards Committees. The work elements included such things as
coordination of me_ ;ihgs (excluding travel); preparation and distribution of documents for
review and ballot; Sl#porting the development of new technical areas for standardization

under these com_ _ittees; review of the feasibility, scope and drafting of new standards;
and preparation r_eports and delrvery of one copy of each newly developed standard to
NASA.
ACCOI ENT8 DURING THE GRANT PERIOD
10 ,rioan National Standards were ,adopted and published
The folrowing National Standards were processed through the working groups
and submitted for )eliot to the Accredited Standards Committees according to the
approved operati; _rocedures of the Committees•

National Standard,' ,and published
These five internatk _alstandards were reviewed by the working groups and submitted
for ballot tothe Accr _¢litedStandards Committees according to the approved operating
procedures of the C mmittees, Many of the Working Group members were also
members of the coi'l ;,_,ponding international working groups and thus were actively
involved inthe dove _Pment of these standards. Where it is possible, the national

On behalf of the AC _stical Society of America Standards Secretariat, Iwant to thank
you for the suppod ou have provided over the last three years. We believe that NASA
can be proud of the a_orkthat was accomplished with this support and hope that NASA
will consider suppc_l ,_ir_gASA Standards in the future.
