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.
