Анализ путей передачи колебаний TPA(Transfer Path Analysis (TPA), also referred to as Noise Path Analysis (NPA), is an experimental technique for identifying the vibro-acoustic transfer paths in a system, from the active system component(s), generating the structural and acoustic loads, through the physical connections and along airborne pathways, to the target point(s) at the passive system component(s) responding to these loads. sega_tarasov)
