Uninzi lwabantu luthatha kancinci ukuba isandi se iinzipho ebhodini ayimnandi, kodwa uninzi alukhange lubuze ukuba kutheni. Kwakungenjalo UMichael Oehler ye IYunivesithi yaseMacromedia yeendaba kunye noNxibelelwano kwaye IYunivesithi yaseVienna uChristoph Reuter , Uphando lwakhe olutsha kwisandi esingathandekiyo sinokufumana ingcambu yokungathandi kwethu.
Kuphando lwabo, iingcali ezimbini zomculo zijonge ukusabela komzimba kunye nengqondo kwizandi ezingathandekiyo. Kuvavanyo lwabo, badlala isandi esinganyanzelekanga sezikhonkwane kwibhodi yabathathi-nxaxheba kunye nezinye izandi ezithiyiweyo ezinje nge-styrofoam engacacanga, iifolokhwe zikrwela kwiipleyiti zesidlo sangokuhlwa, kunye netshokhwe ngokuchasene nesileyiti. Ngamanye amaxesha baxelela abaphendulayo owona mthombo wesandi kwaye kwabanye babaxelele ukuba izandi zivela kumculo. Ekupheleni kovavanyo, abaphandi babeke esweni imiqondiso eyahlukeneyo yabathathi-nxaxheba ngelixa iithoni zazidlalwa.
Iziphumo zazintle kakhulu.Akumangalisi ukuba, icandelo elinamandla lezengqondo lafunyanwa ngabaphandi. Xa babecelwa ukuba babeke izandi kwinqanaba lokungathandeki, abathathi-nxaxheba abaxelelwe ukuba izandi zazivela kumculo ngokwengqekembe bafumanisa ukuba izandi ziyanyamezeleka kunaxa bexelelwa owona mthombo wesandi.
Iziphumo ezincomekayo zafika kwimilinganiselo yomzimba ethathwe ngabaphandi. Bafumene utshintsho olukhulu kwi ukuqhuba kwesikhumba xa kudlalwa izandi ezingathandekiyo, zibonisa ukusabela okungafaniyo komzimba kwisandi. Abaphandi baphinde bacofe uluhlu lokurhabaxa kwesandi esihamba phakathi kolusu 2,000 kunye ne-4,000 Hz - Olu luhlu olufanayo nentetho yomntu. Okumangalisayo kukuba, xa la maxesha ehluziweyo kunye nesandi siphindwa, abathathi-nxaxheba babengenangxaki yokumamela isandi.
Uluhlu lwezandi zezandi ezingathandekiyo lukwabalulekile ngenxa yokwakheka kweendlebe zabantu. Iindlebe zethu zenziwe ngendlela yokuba zikhulise amaza aphakathi kwama-2 000 ukuya kuma-4,000 Hz. Abaphandi bakholelwa ukuba isandi ebhodini, kunye neetoni ezifanayo, azinyamezeleki ngenxa yokuba ukuphakamisa oko kukhulu kakhulu kangangokuba kuya kuba buhlungu.
Lo mjikelo wangoku wophando wakhela kwisixa esikhulu sophando esele senziwe kwi-nail-and-chalkboard reaction. Ngaphambili, nangona kwenziwe ityala, uphando luphonononge umthombo wempendulo engalunganga yomntu kwisandi ngokufana phakathi kwayo kunye neefowuni zesilumkiso. Kutshanje, kunye nophando oluzinzileyo, kufunyaniswe ukuba yayiziindawo eziphakathi eziphakathi ezikhathaza abantu kakhulu.
Ngolu phando, umntu unethemba lokuba isibetho sezandi ezingathandekiyo ekugqibeleni siyakususwa kubomi bemihla ngemihla. Ndimema ikamva ngezixhobo zokucima ingxolo kwigumbi lokufundela ngalinye, eofisini, nasekhaya elinokusikhusela kuluhlu olubi lwamaxesha ahlala ephazamisa imizimba yethu ethe-ethe. Ke kuya kuthini ukuba oko kwenzeka kuluhlu olufanayo nentetho? Zizo iitapile ezincinci xa kuthelekiswa nokungathandeki. Singakwenza oku, bantu; sinobuchwephesha.

- Ngubani okhathalele ulwakhiwo lweendlebe zabantu xa unokuba neendlebe zerobhothi?
- Okwangoku kuneendlebe zerobhothi ezingaphezulu
- Uya kuziqonda ezi zandi, ngokuqinisekileyo
- Eso sandi sikhonkothayo sivela kwisinyi sepiranha
