Some of the criticisms aimed at the International Standard Tapping machine and its use in rating floors against impacts are discussed in this note. Possible alternate test procedures offer some advantages, but the use of the hammer itself has unsatisfactory aspects. Further basic research is necessary and in this note two studies are described. One is an objective examination of the impulses created by the standard hammer when it strikes various resilient coverings placed on a concrete floor. The second is an attempt to define the parameters on which subjects base their evaluation of footstep noise.
