1. Umbhobho omdala kunye nokulinganisa iseva kumbhobho.
2. Izinto zombhobho ziyi-pyknotic kunye ne-symmetrical, kunye nezinye izinto ezimbi ze-acoustical conductivity;
3. Umphezulu wodonga lombhobho unepeyinti yokwaleka;
4. Isicelo asingombhobho wamanzi opheleleyo;
5. Umbhobho ongaphakathi unamaqamza omoya amaninzi okanye izinto eziziqina ekhulwini;
6. Umbhobho/umbhobho othe tye awukho mde ngokwaneleyo.
7. Indawo yokufakela isilinganisi-manzi ikufuphi nomsinga onyukayo wombhobho ofake ivalve;
8. Isiguquli okanye ukuphazamiseka kwengxolo kwisiza.
9. Umlinganiselo ophakathi luhlobo lomxube okanye ulwelo oluthile olunomoya ombi, onjengelindle elikrwada, udaka, uludaka, njalo njalo.
10. Ulwelo lwendlela yokuhamba kombhobho lusuka phezulu ukuya ezantsi okanye lufakwe njengendawo ephezulu yombhobho, nto leyo ebangela ukuba amanzi ombhobho angagcwali okanye amaqamza afunjwe kwindawo yofakelo.
