A Case Study Of The Acoustic Environment In Kindergarten Daily Life

Air,water,food and noise pollution are the four major environmental pollutions recognized by society.The air,water,and food pollution in kindergartens have been highly valued,but the attention to noise pollution is very low.Noise affects the physical and mental health of both teachers and children.Investigation and research on the status of noise in the kindergarten environment will help improve the acoustic environment of the kindergarten.The study uses a noise meter-SNDWAYsw-524 digital noise meter,Used to measure noise decibels per second.Select one kindergarten from small classes,middle classes,large classes,5 days of data per class,Time is fixed between7:30 in the morning and 17:00 in the afternoon,Contains nine activitiesand data logging one per second.Use the launch Noise Meter software to organize all collected noise data into a table,then use SPSS software to make descriptive statistics on the data,The table shows the distribution of noise intensity more intuitively.Descriptive statistics,histograms,etc.are used to describe the overall situation of noise in the kindergarten teacher’s working environment.Multivariate analysis of variance in the impact of age classes and links on noise.Analysis of the impact of links on noise and the interaction between age classes and links on noise.The research results show that:(1)The noise in the kindergarten daily life seriously exceeds the standard;(2)there is a significant difference in the noise status of different age classes,Sort result is:Middle class>Taipan>Small class;(3)there is a significant difference in the noise status in different parts of daily life;(4)small,middle and large age classes Significant interaction with the impact of the link on noise.The noise mean difference ranking results are:Optional Activities> Dining> Education Activities> Outdoor Activities> Leaving the Garden> Transitional Links> Getting Up> Entering the Garden> Siesta.Put forward suggestions for effectively organizing various activities;multi-pronged approach to eliminate indoor noise;multiple considerations to reduce external noise;enhance nutrition and reduce injuries;strengthen the management of related departments,etc.
