I roto i ngā awheawhe nui, he mea nui te pupuri i te rere o te hau me te whai huatanga o te pūngao mō te whakamarie me te whai huatanga o te mahi. Kua puta ake ngā pā hau tuanui ahumahi HVLS hei otinga nui ki ēnei wero, e tuku ana i ngā painga nui hei whakarei ake i te taiao mahi.

Ko tētahi o ngā painga matua o te tāutanga o te pā hau tuanui ahumahi Apogee HVLS ko te pai ake o te tohanga o te hau. He maha ngā wā he teitei ngā tuanui o ngā awheawhe me ngā papa whānui, ka hua ake he putunga hau e noho pūmau ana. Ka āwhina te pā hau Apogee HVLS ki te tohatoha i te hau puta noa i te wāhi, ko tōna haruru ≤38db, he tino marino. Ka whakaitihia e ngā pā hau Apogee HVLS ngā wāhi wera me te whakarite i tētahi taiao mahi whakamarie ake. He mea nui tēnei i roto i ngā ahumahi e mahi ana ngā kaimahi i ngā mahi uaua tinana.
