Abstract:
For the measurement of low frequency impact sound in heavy structures
residential buildings, rubber
ball is used in Korea and Japan. Rubber ball was regulated as standard
heavy/soft impact source in
ISO 10140-5 and ISO 16283-2. Rubber ball impact sound had similar
characteristics with child’s
jumping and running in concrete apartment buildings. However, single number
evaluation method on
rubber ball impact sound was not regulated in ISO standard. In this paper,
based on results of
subjective auditory experiments, single number evaluation method will be
proposed.
