Zvatinoona seruzha mhedzisiro yekuchinja kwemhepo. Nzeve dzedu inhengo dzakatetepa mukati menzeve dzedu dzinotora masaisai ekuchinja kwemhepo inoita kuti dzizununguke. Uku kudedera kunozopfuura nepakati pemamwe mapfupa akapfava mumusoro medu kuti asvike pachikamu cheuropi chinodaidzwa kuti auditory cortex, iyo inoadudzira seizvo zvatinoona sekurira.

Shanduko idzi mukudzvinyirirwa ndizvo zvinoitawo kuti tinzwe ruzha rwakanyanya kana runyoro, semafirework kana mimhanzi pakonzati. Ruzha rukuru runobvisa mhepo yakawanda munguva pfupi-dzimwe nguva yakakwana kuti tinzwe kutenderera mumativi emuviri kunze kwenzeve dzedu. Unogona kunge wakaona masaisai eruzha achimiririrwa semasaisai. Iyo Y-axis pane aya wavy graph inomiririra amplitude yeizwi wave. Muchirevo chechinyorwa chino, inogona kurangarirwa sechiyero chehuwandu hwemhepo inobviswa. Kuwedzerwa kwemhepo kunoreva kurira kwakanyanya uye masaisai epamusoro muchati. Chinhambwe chiri pakati penhongonya pa X-axis chinobva chamiririra kureba kwenzwi. Mitinhimira yepamusoro ine mawavelength mapfupi, mitsindo yakaderera ine marefu akareba.

Echo ine wavelength yakafanana neyainonongedza ruzha wave, asi chikamu chayo cheamplitude chinodzoserwa kumashure. Masignal waveforms akafanana nemifananidzo yegirazi. Izvi zvinoreva kuti kana ruzha rweruzha rwakonzera kusagadzikana kwemhepo, iyo anti-ruzha ruzha wave inokonzera yakanaka air pressure (uye zvinopesana).

Nepo ruzha rwakadzika rwakadzama rwuri nyore kufanotaura uye kudzvanyirira nereverb yakakodzera, zvakanyanya kuoma kudzvanyirira isingaenzaniswi organic background ruzha munguva chaiyo. Nekudaro, maererano nebudiriro yeANC mumakore achangopfuura, tinogona kufunga kuti kudzikiswa uku kuchakundwa nekufamba kwenguva. Uye ingave iri mhinduro kubva kuSamsung kana Apple (avo AirPods vane u Android zvirambidzo zvemafoni), Sony kana chero ani zvake.
