Fitness culture has significantly grown since the nineteenth century. In the recent decade, the gym and fitness industry have thrived in many countries. The construction of gymnasiums has increased dramatically, and fitness centres have become one of the most common spaces in mix-used buildings around the world. There are a significant number of gyms located relatively close to residential areas, some of which have even proposed to operate 24 h a day. The noise and vibration generated by dropping free weights in the gym affect the user experience and the surrounding community to a certain extent. In addition, today’s gyms are frequently operated out of refurbished retail units. Most refurbished unit buildings’ structures were never designed to host a gym, which makes the mitigation of noise and vibration very difficult. Based on critical literature reviews, the use of gymnasiums flooring system is relatively straightforward to mitigate the noise and vibration, but its effectiveness is hardly monitored. This study mainly discusses the use of material for mitigating noise and vibration in the gymnasiums together with the crowd sensing evaluation of vibration effectiveness, uncertainty and material deterioration to manage appropriate level of noise and vibration. The gym at the University of Birmingham has been chosen as a case study. Over 10 h of field tests have been conducted to record data of the operating floor material in the gym and fitness centre using novel smartphone sensors. Considering the specific floor material, a strategy of reducing noise and vibration is proposed. In addition, health and safety assessments are also carried out to evaluate the public safety condition in the gym. The insight into novel crowdsourcing smartphone sensors can help end-users to monitor the environmental impacts around the gyms and surroundings in real time.

体育活动中智能手机的感应和震动噪声的识别

自19世纪以来,健身文化得到了显着发展。在最近的十年中,健身房在许多国家蓬勃发展。体育馆的建设急剧增加,健身中心已成为全球混合使用建筑中最常见的空间之一。许多体育馆都相对靠近居民区,其中一些甚至提议每天24小时开放。在健身房中减轻自由重量产生的噪音和振动会在一定程度上影响用户体验和周围社区。此外,当今的健身房经常是在翻新的零售单元之外运营。大多数翻新的单位建筑物的结构从未设计成可以容纳体育馆,这使得缓解噪音和振动变得非常困难。根据重要的文献评论,体育馆地板系统的使用相对简单,可以减轻噪声和振动,但几乎无法监控其有效性。这项研究主要讨论使用材料来减轻体育馆中的噪声和振动,以及对振动效果,不确定性和材料劣化进行人群感知评估以管理适当的噪声和振动水平。伯明翰大学的体育馆被选为案例研究。使用新颖的智能手机传感器,已进行了10多个小时的现场测试,以记录健身房和健身中心操作地板材料的数据。考虑到特定的地板材料,提出了一种减少噪音和振动的策略。此外,还进行了健康和安全评估,以评估体育馆的公共安全状况。对新型众包智能手机传感器的洞察力可以帮助最终用户实时监控体育馆和周围环境对环境的影响。
