“丢失频率”由HearLife诊所和迪拜的FP7/McCann共同创建，是一系列针对听力损失的自我诊断广播广告。阿联酋有50万人听力受损，HearLife面临的挑战是让35%的患者不知道自己有问题，进行听力测试。
听力损失的早期症状是难以听到高频和低沉的声音，通常只有在听力学检查中才能发现。在检查中，测试了患者听力的声音范围：那些听不到超过4kHz+的人被诊断为听力损失。
为了让这个测试成为每个人都想听的东西，研究小组采用了听力测试的科学方法，并将其伪装成野生动物纪录片。因为鸟类、蟋蟀和海豚都会以4kHz+的频率自然歌唱，所以它们可以利用这些动物来帮助自我诊断听力损失。
在一系列3台收音机中，与海豚一起快速潜水，听鸟叫声，在一个夏天的夜晚加入成千上万只蟋蟀的行列。第一次，那些不知道自己有问题的人进行了自我诊断，并提出了解决办法。
