Hi
I recommend to read
WHEN FROGS SCREAM! A REVIEW OF ANURAN DEFENSIVE VOCALIZATIONS L. F. TOLEDO&C. F. B.HADDAD Berislaw, seems it should be regarded according to this work. Personally I observed also defensive call at adult P. fuscus that I rescued from street drainage. This specimen was vocalizing with mouth closed when touching him. It is thought that I. alpestris can release air from lungs with loud whistle using it to scare attacker. Below is the part of this opus introduction-

Among Old World Salamandridae, only Triturus and Pleurodeles are known to emit sounds according to BRODIE (1977). However, in a summary of the acoustic emissions of Salamandra salamandra, MENGES (1951) reported on a reliable observation by L. MULLER that Salamandra salamandra Corsica (=Salamandra Corsica) regularly produces vocalizations if specimens are stressed. FELDMANN(1968) confirms the occurrence of distress calls in Central European Salamandra salamandra terrestris. Vocalizations in the salamandrid Mertensiella luschani finikensis (Fig. 1) were first mentioned by FRANZEN (1987) and later confirmed by STEINFARTZ & MUTZ (1999). In the present paper we analyze the distress calls of this taxon for the first time.
Have anyone paper about vocalizing among european newts?
