(2004): Spectrographic analysis of the ultrasonic vocalisations of adult
male and female BALB/c mice. Naturwissenschaften, Volume 91 Number 8,
381-385
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
Message-Id:
I have a question. I have been using a Sony TCD-D100 DAT recorder, for about 3
years
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
week
for around 6 hours, playing back the sounds as well as fast forwarding and
rewinding
to find specific time stamps.
In early June the DAT chewed a tape and then within a couple of days, stopped
winding
the tape on. I took the DAT into a service centre who replaced a 'badly worn
drum
assembly' and '2 x cracked gears'. Fair enough as I had been using the DAT
fairly
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
again,
i.e. would not wind the tape on. I took the DAT back to the repair centre who
reported
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
service
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?
Thanks,
Michelle Lemon
