关于客观测试 客观测试用美国LibertyAudio公司的LAUD3.0电脑测试系统来进行。LAUD是基于MLS方法的测试系统,可以在非消声室测量音箱的频响、阻抗、失真度等多项特性,计算并绘制音箱的相位特性、后沿累积谱等曲线图。我们着重考查阻抗、频响和后沿累积衰减谱(俗称瀑布图)这三种特为一台Densen DM-10,测试环境为一间40m~2左右的空旷房间。MLS
Objective test Objective test with the United States LibertyAudio LAUD3.0 computer test system to carry out. LAUD is a MLS-based test system that can measure and characterize the speaker’s phase characteristics, back-porch cumulative spectra, etc. in a non-anechoic chamber to measure the loudspeaker’s frequency response, impedance, distortion, and more. We focus on examining the impedance, frequency response and cumulative attenuation spectrum (commonly known as the waterfall map) These three special for a Densen DM-10, the test environment for a 40m ~ 2 empty room.
