Voluntary Standards Cover the Spectrum: from Evaluating Room Noise to Towing Farm Equipment


9/23/2019

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Room Noise
In environments such as classrooms and offices, and even more high-stakes settings like operating rooms, it is critical to keep noise levels to a minimum so that occupants can concentrate on their work. Other environments, such as workplaces where tools and machinery are frequently used, may present occupational hazards when room noise levels become too high. It is essential to accurately measure room noise in any of these instances to assure that an environment is suitable for its occupants’ health, safety, and needs. ANSI/ASA S12.2-2019, Criteria for Evaluating Room Noise, was developed by ANSI member and accredited standards developer the Acoustical Society of America (ASA). This document provides three primary methods for evaluating room noise: a survey that employs the A-weighted sound level; an engineering method that employs expanded noise criteria (NC) curves; and a method for evaluating low-frequency fluctuating noise using room noise criterion (RNC) curves.

ASA is a membership society committed to increasing and diffusing the knowledge of acoustics and its practical applications, as well as fostering studies of noise, its measurement, its effects, and ways of reducing noise to improve the human environment. ASA serves acoustics professionals throughout the U.S. and abroad in a variety of fields related to sound including physics, engineering, robotics, oceanography, architecture, music, noise control, and many others.

Towed Farm Equipment
As the fall harvest season begins, drivers may encounter farm equipment on public roadways. Farmers transporting a combine or harvester towing an unpowered implement may use roads to get from farm to field, or from one field to another. A new American National Standard developed by the American Society of Agricultural and Biological Engineers (ASABE) guides particular hitching systems for farm equipment being towed on the road. ANSI/ASABE S638 MAY2019, Pintle Hitch and Ring for Over the Road Towed Implements, establishes requirements for pintle hitching system – one that uses a tow ring configuration to secure to a hook or ball combination. Pintle hitching is ideal for heavy-duty towing, especially on rough or off-road terrain.

ASABE, an ANSI member and accredited standards developer, is dedicated to the advancement of engineering for agricultural, food, and biological systems. The membership organization is open to all stakeholders interested in the technologies for these systems, which support the production of food, fiber, timber, and renewable energy sources through efficient and environmentally sensitive methods.
