Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Vanotsvakurudza vanoshandisa mahydrophone (anowanzoshandisirwa kushandiswa nemauto pakutevera ngarava dzinofamba nepasi pegungwa) kuti vaone nzvimbo chaiyo inobva mheremhere dzemapere. Nzira dzavanoshandisa dzinovagonesawo kuona kuti ruzha runofamba rwuri kure zvakadini mugungwa. Kutsvakurudza kwakaitwa naDr. Christopher Clark veCornell University vachishandisa mashoko ehondo kwakaratidza kuti ruzha rwehove rwunofamba zviuru zvemakiromita. Kunze kwokupa mashoko anoratidza kuti hove idzi dzinoimba sei, mashoko aya anobatsira vaongorori kuti vazive mafambiro anoita hove idzi panguva yadzinenge dzichiimba. Chimwe chinhu chinokosha chakawanwa ndechokuti marwenga, mukuita kunonzi Lombard effect, anochinja rwiyo rwawo kuti agadzirise kusvibiswa kwemheremhere. Uyezve, pane uchapupu hwokuti hove dzebhuruu dzinorega kuita D dzinodana dzinotsvaka zvokudya kana mid-frequency sonar yaitwa kuti ishande, kunyange zvazvo sonar frequency range (1<unk>8 kHz) ichipfuura zvikuru nzvimbo yadzo inobudisa ruzha (25<unk>100 Hz).Pamberi pekuunzwa kwevanhu vanogadzira ruzha, Clark anoti ruzha rwacho runogona kunge rwakatama ruchibva kune rumwe rutivi rwegungwa kuenda kune rumwe rutivi, ruchibvumirana nepfungwa yemakore makumi matatu yekupomera kutakura kukuru. Kutsvakurudza kwake kunoratidza kuti ruzha rwomumhoteredzo runobva muzvikepe ruri kupetwa kaviri negumi rimwe nerimwe ramakore. Izvi zvinoderedza nzvimbo inonzwika mhere-mhere dzemapere. Vanoona nezvezvakatipoteredza vanotya kuti kufamba nengarava kwakadaro kuri kunyanya kunetsa mhuka idzi uye kuri kuita kuti zviome kuti dziwane munhu wokuroorana naye. Mumakore gumi apfuura, pane nzira dzakawanda dzinoshanda dzinoshandiswa nemichina, dzakadai sokushandisa masaini, kutsvakurudza mashoko, uye kushandisa michina kuti uzive kuti whale inenge ichitaura sei.  Mubvunzo: Ruzha runowedzera zvakadini mumakore gumi?
