Problems solved by technology

In 2009, Korean scholars such as JinYongJeon used a 21mm diameter steel ball to simulate a 1:10 scale artificial head, placed two 1 / 8-inch microphones at symmetrical positions on both sides of the steel ball to receive binaural signals, and explored the impact of changes in sound field conditions on binaural The effect of the ear cross-correlation parameter IACC; but the microphone is not placed in the ear canal, there is still a big difference between the scale artificial head and the real artificial head (see Image 6 )

Embodiment Construction

[0026] The purpose of the invention of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the embodiments cannot be repeated here one by one, but the implementation of the present invention is not therefore limited to the following embodiments.

[0027] A method for manufacturing an architectural acoustic 1:10 scale artificial head, comprising the steps of:

[0028] A. Use a three-dimensional laser scanner to scan the full-scale standard artificial head prototype, such as the 01dB-MK2B full-scale standard artificial head prototype. The target acquisition accuracy of the scanner is ±1.5mm, and the minimum sampling density during scanning is figure 1 );

[0029] B. Import the DXF file into 3DMAX for 3D patch editing and processing to obtain an accurate 3D curved surface digital model of the artificial head. When modeling, reserve the ear canal 2 in the human head, the opening of the ear cana...

Abstract

The invention discloses a method for manufacturing an architectural acoustics 1: 10 reduced ruler head and torso simulator. The method comprises the first step of scanning a full-size standard head and torso simulator prototype through a three-dimensional laser scanner and storing the scanned data file as a DXF; the second step of guiding the DXF into a 3DMAX so that three-dimensional patch editing can be carried out on the DXF and an accurate three-dimensional curved surface digital model of the head and torso simulator can be obtained, wherein an auditory meatus is reserved in the head and torso simulator in the process of modeling; the third step of manufacturing the 1: 10 reduced ruler head and torso simulator through a 3D printing machine according to the designed three-dimensional digital model in a proportional zooming mode; the fourth step of vertically placing two microphones connected with rotary unions into the auditory meatus pre-reserved in the 1: 10 reduced ruler head and torso simulator to serve as a binaural signal receiver simulating the full-size head and torso simulator; the fifth step of plugging filler into a chest of the 1: 10 reduced ruler head and torso simulator. The 1: 10 reduced ruler head and torso simulator can be used for measuring hall space sense parameters in an acoustics reduced ruler model experiment and will be applied to the auralization technology.

Description

technical field [0001] The invention relates to a technique for measuring spatial sense parameters of an architectural acoustic scale model, in particular to a method for manufacturing an architectural acoustic 1:10 scale artificial head. Background technique [0002] Scale model experiment is one of the main prediction methods of architectural acoustics. In the world, acoustic scale model experiments are usually done for more than 1,500 halls with natural sound performances. The scale model experiment is to reduce the actual hall according to a certain ratio, determine the corresponding material of the interface according to the similarity law, then use the high-frequency sound source to make sound, and record the impulse sound in the model to judge the acoustic defects and predict the acoustic parameters. Limited by sound sources and microphones, scaled model experiments can only be used for the measurement of single-channel impulse responses, so they can only be used for...
