The path of acoustic waves within the sun is not straight, and different wave modes travel at different speeds and to different distances from their source before reaching the surface of the sun; nor is it possible to place a reflecting or refracting lens into the sun to collect acoustic waves.
由於太陽內部震波軌跡並非直線，不同模式的波抵達太陽表面的距離與時間也不同，更不可能在太陽內部放置反射鏡或透鏡來收集震波。
