Impact Power Characteristics by Walking for Adults

Impact sounds, such as those created by footsteps, the dropping of an object or the moving of furniture, can be a source of great annoyance in residential buildings. Running and jumping impact sound by child and walking by adult are one of the most irritating noises in an apartment buildings. It's necessary to know that the impact power characteristics of real impact source in an apartment buildings. This study aims to investigate the impact power and impact time of normal walking and fast walking for 62 adults. It is shown that when the weight of the person increase, the maximum impact power increases. The impact power waveform for the adults walking varies for subjects walking types. The normal walking impact power lower than that of fast walking and impact time is higher than that of fast walking. The range of the impact power generated by adults walking is less than 1000 N.
