 (2004): Spectrographic analysis of the ultrasonic vocalisations of adult
 male and female BALB/c mice. Naturwissenschaften, Volume 91 Number 8,
 Abstract: In this study, a spectrographic analysis was designed to
 improve the description of the shape, the modulations, the rate, length
 and frequencies of BALB/c mouse calls in different behavioural
 situations. Male and female calls emitted during investigation of cages
 with clean bedding, soiled with male or female bedding, and during
 same-sex encounters, were recorded and described. BALB/c male mice
 uttered different types of vocalisations both when investigating
 counterpart odour cues and when interacting with same-sex counterparts.
 BALB/c female mice vocalised solely during same-sex counterpart
 encounters and it appeared that calls were uttered mainly by the
 resident females. Male and female mice present a complex array of calls,
 which seem to be linked to particular behavioural situations. Further
 studies using this technology may help to improve our understanding of
 the role of vocal communication in natural rodent populations.

Subject: problems with DAT recorders

 I have a question. I have been using a Sony TCD-D100 DAT recorder, for about 3 
 recording dolphins & underwater sound in the field (~ 4 months a year). Being 
used on 
 a small boat it was exposed to salt air. 
 Early this year I began my analysis, and as such, using the DAT about 5 days a 
 for around 6 hours, playing back the sounds as well as fast forwarding and 
 to find specific time stamps. 
 In early June the DAT chewed a tape and then within a couple of days, stopped 
 the tape on. I took the DAT into a service centre who replaced a 'badly worn 
 assembly' and '2 x cracked gears'. Fair enough as I had been using the DAT 
 continuous for a number of years and it was no doubt in need of a service.
 However, 3 ½ weeks later in the middle of my analysis, the DAT stopped working 
 i.e. would not wind the tape on. I took the DAT back to the repair centre who 
 that the drum was badly worn again * the same problem! The technician 
explained that 
 it must by my tapes that are causing the problem through contamination. 
Although I 
 find it difficult to believe that the problem has occurred again after only 3 
½ weeks 
 of use, which was not continuous, perhaps 4-5 hours a day, 5 days a week. The 
 centre nor Sony will now replace the faulty drum.
 Has anyone else experienced problems such as this? Or does anyone have any 
advice as 
 to why the problem has occurred? Or had problems with contaminated tapes?
