Method and system for improving indoor speech articulation
The invention discloses a method for improving indoor speech articulation. The method comprises steps as follows: geometrical size of an interior building is acquired, and an indoor simulation model is established according to the geometrical size; a plurality of parameter evaluation points are selected from the indoor simulation model, and a plurality of articulation weak points are selected fromthe parameter evaluation points according to a preset articulation evaluation parameter calculation strategy; the articulation weak points are used as reference positions for indoor layout of diffusers and reflection materials; average reverberation time of the articulation weak points at an octave frequency band is calculated; sound absorption increment corresponding to the octave frequency bandis calculated according to preset target reverberation time of the octave frequency band and the average reverberation time; a sound absorption material is selected according to the sound absorptionincrement; and the sound absorption material is used for being arranged in a first preset position of the interior. The invention further discloses a system for improving the indoor speech articulation. With adoption of the embodiment, the indoor speech articulation can be effectively improved.
本发明公开了一种提升室内语言清晰度的方法，包括：获取室内建筑的几何尺寸，根据所述几何尺寸建立室内仿真模型；在所述室内仿真模型中选择若干个参数评价点，根据预设的清晰度评价参数计算策略在所述参数评价点中选取若干个清晰度薄弱点；所述清晰度薄弱点用于作为在室内布置扩散体和反射材料的参考位置；计算所述清晰度薄弱点在所选倍频程频带下的平均混响时间；根据预设的所述倍频程频带的目标混响时间和所述平均混响时间计算所述倍频程频带对应的吸声增量；根据所述吸声增量选择吸声材料；所述吸声材料用于布置在室内的第一预设位置处。本发明还公开一种提升室内语言清晰度的系统。采用本发明实施例，能有效提升室内的语言清晰度。
