Analysis On Soundscape Quality Of Forest

Environmental quality is demand more high with the development of economy and society. People hope a good visual landscape outside and good hearing landscape. We have a higher requirements and expectations forest sound environment to meet the needs of the people on the hearing environment. Forest is the beautiful sound environment, and sound forest landscape is an important component of forest environmental factor. The importance and effect of landscape forest sound were gradually known by people. This paper researched and analysis acoustic landscape subjective quality and natural objective quality by investigation and field forest acoustic landscape voice acquisition in SanZhaoLun national forest park.The first, we analysis forest acoustic landscape classification base on field investigation and voice of forest acoustic landscape.1. We classify the forest landscape resources classification as nine categories of acoustic landscape forest by GIS information database base on the forest structure and spatial pattern classification,2. We classify the forest of acoustic landscape as seven base on the actural acquisition voice to A sound level for quantitative index classification analysis and base on A sound level for quantitative index quantitative calculation,.3. We classify the voice of forest landscape resources classified as three categories,38small class of acoustic landscape forest base on sound field survey of forest landscape of classification.4. We classify the forest of acoustic landscape cognitive map result classification as five categories.Second, forest acoustic landscape subjective quality analysis1. We classify the forest landscape resources classification as five categories, and forest acoustic landscape as three categories base on the forest of acoustic landscape of be fond of subjective quality by using radar map analysis, fuzzy clustering analysis, system cluster analysis, variable clustering analysis.2. We classify effect of acoustic landscape forest degree of be fond as the two big main composition, and two big main factor base the influence degree of be fond of acoustic landscape forest of subjective factor of quality research by the application of composition analysis, factor analysis, project analysis analyzed the degree of be fond of forest acoustic landscape project rationality.3. The uncertainty variables of influence voice forest landscape feeling are gender, age, occupation, education, personality, hobbies. We analysis the cross influence factor using multiple response.4. We research the forest acoustic landscape perception attribute dimension reach two perception attribute dimension and forest landscape classification.5. Forest acoustic landscape semantic segmentation analysis results:forest acoustic landscape connotative and denotative meaning are:(1) forest landscape with quiet, natural, quiet, beautiful, friendly, happy and connotative and denotative meaning.(2) forest landscape with pure, smooth, soft, slow, close, the social and connotative and denotative meaning.Third, the forest acoustic landscape objective quality analysis1. The analysis of voice premise of acoustic landscape of physical indexWe choose the sound of bamboo forest landscape as analysis object, and analysis, draw out various kinds of graphics, such as sound wave diagram, spectrum diagram, mplitude diagram, amplitude histogram of acquisition of wav Audio file using Audio, goldwave software.2. The analysis of voice of acoustic landscape of non-stationary characteristicsWe analysis wav sound file of Fourier transform, inverse Fourier transform, short time Fourier transform, wavelet, Hilbert transform, envelope, extraction frequency and wavelet by origin8.5software.3. We analysis the relationship of forest different acoustic landscape by convolution, coherence and correlation analysis and the time domain and frequency omain contrast by Matlab2011b.Fourth, the acoustic landscape forest conservation and utilization1. We carry out five different frequency of bamboo birdsong uses by wavesurfer preliminary and Praat, which can through the analysis of forest sound tweedle that bird diversity. The wavelet analysis can be further positioning and amplification analysis through the3D profile of forest acoustic landscape.2. We explore voice of forest landscape in comprehensive utilization and edit analysis with widi4.1, will the original voice of forest landscape into staff and MIDI spectrum, and can play on the computer.We analysis types of forest acoustic landscape and affect the quality factors, acoustic landscape forest the connotative and denotative meaning in the different perspective. We analysis the sound quality of the smoothness of physical index and smoothness characteristics of a variety of signal in forest landscape. Try to play the forest of acoustic landscape to vocal music to acoustic spectrum realization way.
