Kule mihla, kukho iindidi ezimbini eziqhelekileyo zezithethi kwimarike: izithethi zeplastiki kunye nezithethi zokhuni, ngoko zombini izixhobo zinenzuzo yazo.

Izithethi zeplastiki zinexabiso eliphantsi ngokwentelekiso, ubunzima obukhaphukhaphu, kunye neplastiki eyomeleleyo.Zintle kwaye zahlukile ngenkangeleko, kodwa nangenxa yokuba zenziwe ngeplastiki, zilula ukuzonakaliswa, zineziphene eziphila ixesha elide, kwaye zinesandi esibi sokufunxa.Nangona kunjalo, oko akuthethi ukuba izithethi zeplastiki ziphantsi.Ezinye iimpawu zangaphandle ezaziwayo zisebenzisa izixhobo zeplastiki kwiimveliso eziphezulu, ezinokuthi zivelise isandi esihle.

Iibhokisi zesithethi zeplanga zinzima kunezo zeplastiki kwaye azithandeki kangako ekugqwetheni kwesandi ngenxa yokungcangcazela.Zineempawu ezingcono zokumanzisa kunye nomgangatho wesandi esithambileyo.Uninzi lweebhokisi zamaplanga zamaxabiso aphantsi kule mihla zisebenzisa i-medium density fiber njengempahla yebhokisi, ngelixa amaxabiso aphezulu asebenzisa umthi osulungekileyo wokwenyani njengempahla yebhokisi.Uxinaniso oluphezulu lwemithi ecocekileyo lunokunciphisa i-resonance eyenziwa sisithethi ngexesha lokusebenza kunye nokubuyisela isandi sendalo.

Kule nto, kunokubonwa ukuba inxalenye enkulu yokukhethwa kwezinto kwibhokisi yesithethi iya kuchaphazela umgangatho wesandi kunye ne-timbre yesithethi.
