Real-ear attenuation at threshold (REAT) and monaural pure-tone thresholds were determined for normally hearing adults using a supra-aural, Audiocup, and insert earphone. The thresholds were obtained in quiet and in background noises approximating the maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room specified by ANSI S3.1-1991 and OSHA (1983). The supra-aura...

HIGHLIGHTS Proposition of a set technical and managerial actions for an energy management system. A Delphi study with Brazilian PhD specialist academia industry referendum. Approaches based on ISO 50001 ANSI/MSE 2000.

Many fall protection training programs offered today are highly focused on regulatory requirements or exclusively on equipment. But, the most effective training covers these topics and much more. This paper will compare OSHA regulations and ANSI standards, including the new ANSI Z359.2 standard as it pertains to fall protection training. Using lessons learned from an aircraft engine manufacturi...

This paper presents a model checking tool, SatAbs, that implements a predicate abstraction refinement loop. Existing software verification tools such as Slam, Blast, or Magic use decision procedures for abstraction and simulation that are limited to integers. SatAbs overcomes these limitations by using a SAT-solver. This allows the model checker to handle the semantics of the ANSI-C standard ac...

On March 13, 2015, OSHA published in the Federal Register a notice of proposed rulemaking (NPRM) to revise its eye and face protection standards for general industry, shipyard employment, marine terminals, longshoring, and construction by updating the references to national consensus standards approved by the American National Standards Institute (ANSI). OSHA received no significant objections ...

Failure to disclose patents According to ANSI, only certain, limited sanctions are appropriate when a patent owner fails correctly to identify and disclose patent rights embodied into a standard until after the standard has been adopted. (This is the pattern of conduct that led to the US Federal Trade Commission’s 1995 case against Dell Computer after the 1992 development and adoption of the VE...

In this paper the authors propose an algorithm for packet loss concealment (PLC) in transmission over IP-based networks with high packet loss rate. The algorithm is a sender-receiver-based extension of ANSI T1.521a Annex B PLC standard for G.711 voice codec. It consists in adding to a transmitted packet redundant parameters describing speech signal in another packet. Efficiency of the proposed ...

The purpose of this study was to obtain normal hearing thresholds for an ER-3A insert earphone as a contribution for future standardization and for comparison with previous studies and interim ANSI and ISO insert earphone reference equivalent threshold sound pressure levels (RETSPLs). Hearing thresholds were obtained on each ear of 48 normal-hearing subjects from 125 to 8000 Hz using ER-3A and ...
