Rejskovití hmyzožravci (Soricidae) vydávají v nejrůznějších situacích mnoho typů hlasů. Dospělí jedinci se ozývají, pokud jsou v nebezpečí nebo se dostanou do potyčky s jiným jedincem svého druhu, během námluv a páření nebo při kontaktu s potomky. Také mláďata vydávají nejrůznější hlasy, jimiž se často snaží upozornit na své strádání nebo udržet kontakt s matkou a sourozenci. Přestože v poslední době přibývá publikací zabývajících se problematikou akustické komunikace rejskovitých, je to stále poměrně neprobádaná oblast. Mnohé otázky by mohly být zodpovězeny studiem bělozubky hnědé (Suncus murinus), která dobře prospívá i v péči člověka.

Shrews (Soricidae) utter many types of vocalization in various situations. Adult individuals emit vocalizations when they are in danger or in a fight with conspecifics, during courtship and mating or when they keep contact with their offspring. Juveniles utter variable vocalizations mostly to prevent their discomfort and to keep contact with their mother and siblings. Although the number of publications has increased recently, acoustic communica­tion among shrews still remains a quite unexplored field. Our knowledge might be significantly expanded by studying the Asian House Shrew (Suncus murinus), a species that can be successfully kept and bred in captivity.
