Tovushning yer sirtidan turli balandliklar -h da havodagi tezligi - c
Jadvaldagi qiymatlar standart atmosferaga nisbatan muofiqlashtirilgan[1]. Bunda, shartli ravishda balandlik uchun hisob boshi dengiz sathidan boshlanadi, harorat 15 °C, atmosfera bosimi esa 101325 Pa (1 atmosfera) deb olinadi.

Izoh: Troposferada havo harorati balandlik ortishi bilan kamayib boradi, shu sababli balandlik ortishi bilan u joyda tovush tezligi ham kamayadi: har 250 metrda tovush tezligi tahminan 1 msoniya ga kamayadi. 11-20 km balandliklarda standart atmosferaga binoan harorat o‘zgarmas hisoblanadi va u 56.50 °C ga teng. 11-20 km balandliklarda tovush tezligi qiymati ham doimiydir va u 295.07 msoniya ga teng.
