New Guide for Field Measurement of Impact Sound and Vibration Transmission Through Floor-Ceiling Assemblies and Associated Structures When Using Heavy-Hard Impact Objects
1. Scope
This guide covers the measurement of impact sound and vibration generated by a standard heavy-hard impact object through an impact floor and intermediate structures in field situations.
Results are measurable for all types of impact floors, including resonantly and locally reacting floors.
Any single field measurement only represents the performance of the actual assembly, sensor location(s), and impact location(s) tested and shall not be used alone to accurately predict how an identical or similar assembly might perform.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This standard guide does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard guide to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This international guide was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Rationale
Over the last decade, there has been increased interest in assessing buildings due to heavy-hard impact sources, such as free-weight drops and weight stacks in variable lifting machines. Over this decade, there has also been a significant body of research conducted on this topic. This guide uses this research to create suggestions for best practices so that data can start to be standardized across buildings and operators/acoustical consultants. Currently, there is no set object, surface hardness, mass, height, sound/vibration level meter settings, or number of repeat testing needed. This guide does that. This guide is not attempting to fully characterize a building.
The title and scope are in draft form and are under development within this ASTM Committee.
