Voluntary Standards cover speakerphones and ventilation.
Press Release Summary:
September 29, 2011 - To help ensure that speakerphone conversations can be heard loud and clear, IEEE has released IEEE 1329-2010, which provides techniques for measuring electroacoustic and voice-switching characteristics of speakerphones that connect directly or indirectly to analog or digital telephone network. ANSI/AIHA Z9.9-2010, Portable Ventilation Systems, describes fundamental good practices related to design, manufacture, maintenance, use, and testing of portable ventilation systems.

Voluntary Standards Cover the Spectrum: from Speakerphones to Portable Ventilation
Press release date: September 23, 2011
Few telephones are manufactured today without speakerphone capabilities. At the push of a single button, speakerphones allow multiple people to participate in a conversation at once, or a single speaker to hold a hands-free conversation. To help ensure that speakerphone conversations can be heard loud and clear, ANSI member and accredited standards developer IEEE has released IEEE 1329-2010, Standard Method for Measuring Transmission Performance of Speakerphones. IEEE 1329-2010 provides techniques for measuring the electroacoustic and voice-switching characteristics of speakerphones that connect directly or indirectly to an analog or digital telephone network. Due to the various characteristics of speakerphones and the environments in which they operate, not all of the test procedures in this standard are applicable to all speakerphones. Application of the test procedures to atypical speakerphones should be determined on an individual basis. IEEE is a professional association dedicated to advancing technological innovation and excellence for the benefit of humanity through the electrical, electronic, and computing fields, and related areas of science and technology that underlie modern civilization. IEEE and its members inspire a global community through IEEE's highly cited publications, conferences, technology standards, and professional and educational activities. Portable Ventilation
Ventilation is one of the most important factors for maintaining acceptable indoor air quality and ensuring occupant health and safety. Portable ventilation devices can be used in a variety of applications to remove unpleasant smells and excessive moisture, introduce outside air, keep interior building air circulating, and prevent stagnation of the interior air. ANSI/AIHA Z9.9-2010, Portable Ventilation Systems, describes fundamental good practices related to the design, manufacture, maintenance, use, and testing of portable ventilation systems. Published by the American Industrial Hygiene Association (AIHA), the standard is intended for use by facility owners, industrial hygienists and safety professionals, maintenance personnel, and end-users, among others. AIHA, an ANSI accredited standards developer and organizational member, is a non-profit membership organization serving the needs of occupational and environmental health and safety professionals practicing industrial hygiene in industry, government, labor, academic institutions, and independent organizations. AIHA's ANSI/AIHA Z9 family of standards, encompasses standards for the design, operation, and maintenance of equipment to provide a safe atmosphere in industrial, manufacturing, or construction operations by removing harmful substances for the protection of workers by portable or general ventilation, and safely disposing of such substances.
