Von Meerschweinchen und Techno

Bei meiner Recherche nach wissenschaftlichen Studien zur Techno-Szene stoße ich hin und wieder auf wirklich interessante bis kuriose Untersuchungen. Hier gebe ich mal eine kleine Auflistung wieder, da es sich kaum lohnen würde für jede einzelne Studie ein extra Posting zu schreiben. Gleichzeitig sind die Studien aber durchaus interessant, also los gehts:

Hier wurde untersucht, inwiefern Lautstärke und Alkoholeinfluss miteinander korrelieren und sich auf Lautstärkeschwellen auswirken. Dafür wurden 24 Meerschweine in 3 Gruppen aufgeteilt und White Noise bei einer Lautstärke von 105 dB (!!) 30 Minuten lang ausgesetzt. Ein paar wurden vorher zu Alkoholikern erzogen, anderen nur zu Gelegenheitssäufern. Die dritte Gruppe wiederum waren nervige Anti-Alkohol-Abstinentler, die "control group".

Das Ergebnis:

In summary, we have found that acute and chronic treatment of alcohol in combination with noise did not significantly exacerbate TTS or decrease DPOAE amplitudes relative to noise exposure alone.

TTS = Temporäre Schwellenänderungen / DPOAE = CLICK,

Eure Geräuschwahrnehmung wird also laut den Meerschweinchen durch Saufen nicht signifikant beeinflusst. Hier das ganze Abstract:

The purpose of this study was to investigate the effects of concomitant exposure to noise and alcohol on the auditory thresholds. Twenty-four guinea pigs were equally divided into three groups: the acute intoxication group, the chronic intoxication group and the control group. Animals in the acute group received single intraperitoneal injections of ethanol (2 g/kg). In the chronic group, alcohol was administered via drinking water (10%, v/v) over a 60-day period. All animals were exposed to a white noise at the intensity of 105 dB A for 30 min. Auditory brainstem response (ABR) thresholds and distortion product otoacoustic emission (DPOAE) levels were measured before, immediately after noise exposure and also 1, 2, and 7 days following exposure. The results showed: first, acute alcohol injection caused a significant, temporary elevation of ABR threshold (4.8 dB in average), while chronic alcohol treatment did not change auditory threshold significantly. Second, noise exposure induced a mean threshold shift of 15.4- 19.7 dB. ABR threshold returned to normal 2 days after exposure. Both acute and chronic alcohol treatment did not alter the magnitude and time course of recovery of the temporary threshold shift (TTS). Third, the mean DPOAE amplitudes decreased at most frequencies following acute injection of alcohol. However, the differences did not reach statistical significance. Fourth, the mean DPOAE levels dropped 3.4-9.6 dB in all groups after noise exposure and returned to normal 1 day to 2 days after noise. There were no significant differences in the amount of DPOAE suppression after noise between the three groups. In summary, we have found that acute and chronic treatment of alcohol in combination with noise did not significantly exacerbate TTS or decrease DPOAE amplitudes relative to noise exposure alone.

Eine weitere Studie erwähnenswert in diesem Zusammenhang ist die Feststellung, dass sich das Ohr an zunehmende Lautstärke  temporär gewöhnt, anpasst, und nach einigen Tagen wieder entwöhnt. Untersucht wurden 30 professionelle brasilianische DJs:

Statistical analysis showed significant bilateral temporary threshold shifts at all frequencies between audiometry performed pre- and post-exposure to amplified music. Transient otoacoustic emissions showed a significant difference in bilateral amplitude and reproducibility at all frequency bands tested. The comparison of distortion product otoacoustic emissions results pre- and post-music exposure showed there was a significant difference in amplitude. Music exposure was associated with temporary and permanent auditory dysfunction among professional DJs.

Gibt es Unterschiede im Drogenkonsum zwischen einzelnen Musikstil-Kulturen?

Overall, when all other factors were controlled, punk/hardcore, techno/hardhouse, and reggae were associated with more substance use, while pop and classical music marked less substance use. (…) The types of music that mark increased substance use may vary historically and cross-culturally, but, in general, preferences for nonmainstream music are associated positively with substance use, and preferences for mainstream pop and types of music preferred by adults (classical music) mark less substance use among adolescents.

Alter, Geschlecht und Drogenkonsum:

Drug use in these nightlife settings is higher than in the general population. In younger age groups, the illegal drug use increases, but it decreases in older age groups. This might be linked to more responsibilities. Men still use drugs more often than women, but the gender differences seem to decrease. The changing role of women in society could be an explanation for this evolution. (LINK)

Und schließlich: Warum nehmen manche Clubgänger gar keine Drogen? (LINK)

Principal components analysis identified three main factors associated with non-use: rationality (factor score 0.491), lack of opportunity (0.229) and fear of the effects of ecstasy (0.211).
