The temporary or permanent effects of strong noise from MRI devices on hearing functions, especially for different age populations (e.g. neonate and adult) remain unclear. Here we conduct a longitudinal study targeting 3T MRI to disclose such effects on hearing functions of young adults and neonates. Results indicate that due to immaturity of hearing nerve system, neonates show weaker sensitivity to acoustic noise than adults. The 3T MRI noise resulted in transient decrease of young adults’ hearing function (i.e. temporary threshold shift), whereas showed rarely effects on neonates.
