Effects of sound level on postural stability<p>Ses seviyesinin denge performansına etkisi
Journal Title: Journal of Human Sciences - Year 2017, Vol 14, Issue 1
Abstract
The aim of this study is to investigate whether the intended ambient sound level has an effect on the postural stability. For this purpose 15 man and 12 women totally 27 healthy, voluntary students voluntarily participated in the study. The DT-8820 Multi-Function Environment Meter was used for Sound Level Measurement. Quiet environment, while the volume was maintained at between 15-30 decibel noise level of 90-100 dB in noisy environments. The Biodex balance system (Biodex, Inc., Shirley, New York) was used for postural stability measurement. SPSS 21.0 package program was used in the analysis of the data. The Wilcoxon Signed Ranks and Mann Whitney U test was used to compare measurement Significance level was set at 0.05 and 0.01 levels. When the balance performances at different sound levels are compared by gender, It was found that there was a significantly meaningful result in favor of men in quite environment oscillation balance scores both open eye and closed eye. However there was no significant difference among man and women other scores. On the other hand it was determined significant differences in the women closed eye oscillation score. In the man excepting open eye oscillation score the noisy environment was negatively affected all parameter. Postural stability was negatively affected noisy environment. As a result; In the study conducted that the high level of sound impaired the balance performance by affecting the vestibular system in both women and men and the effect was higher when closed eyes. ÖzetYapılan çalışmanın amacı ortam ses seviyesinin denge performansına etkisinin olup olmadığının araştırılmasıdır. Bu amaçla çalışmaya 15’i erkek, 12’si bayan toplam 27 öğrenci alınmıştır. Ortam Ses Seviyesi Ölçümü DT-8820 Multi-Function Environment Meter cihazı ile yapıldı. Sessiz ortam ses seviyesi 15-30 desibel arasında iken gürültülü ortam ses seviyesi 90-100 desibel arasında tutulmuştur.Denge ölçümü için BİODEX denge sistemi (Biodex, Inc, Shirley New York) kullanılmıştır.Verilerin analizinde SPSS 21.0 paket programı kullanıldı. Verilerinin kıyaslanmasında Wilcoxon Signed Ranks Test ve Mann Whitney U test kullanıldı. Anlamlılık düzeyi 0.05 ve 0.01 seviyesinde kurgulandı. Sessiz ortam salınım değerlerinde hem gözler açıkken hem de gözler kapalıyken ölçülen değerlerde erkekler lehine anlamlı bir sonuç olduğu tespit edilirken diğer değerlerde cinsiyetler arası farklılık olmadığı tespit edilmiştir. Diğer taraftan kadınlarda ortam ses seviyesinin gözler kapalı iken ölçülen salınım denge değerlerinde anlamlı farklılık olduğu, gürültünün denge performansını olumsuz etkilediği, erkeklerde ise gözler açık salınım denge değeri hariç hem statik hem dinamik hemde gözler kapalı salınım denge değerlerinde anlamlı farklılık olduğu, dengenin gürültüden olumsuz etkilendiği tespit edilmiştir. Sonuç olarak; yapılan çalışmada yüksek ses seviyesinin hem bayanlarda hem de erkeklerde vestibüler sistemi etkileyerek denge performansını bozduğu, bu etkinin gözler kapalıyken daha yüksek olduğu tespit edilmiştir.
