论文摘要
我们引入了一种新的声学测量方法,该方法可以同时测量线性时间不变的响应,非线性时间流动响应以及随机和随机变化的响应。该方法使用一组由一组单位FVN(天鹅绒噪声的频域变体)制成的正交序列,这是TSP的新成员(时间拉伸脉冲)。 FVN具有其他TSP成员没有的独特功能。这是一个高度的设计自由,可以在不引入额外设备的情况下使提出的方法成为可能。我们使用两个和四个正交序列介绍了两个有用的案例,并说明了它们使用模拟和声学测量示例的使用。我们根据提出的方法开发了一种交互式和实时的声学分析工具。我们将其提供在开源存储库中。提出的响应分析方法是一般的,并且适用于其他领域,例如听觉反馈研究以及声音记录和编码的评估。
We introduce a new acoustic measurement method that can measure the linear time-invariant response, the nonlinear time-invariant response, and random and time-varying responses simultaneously. The method uses a set of orthogonal sequences made from a set of unit FVNs (Frequency domain variant of Velvet Noise), a new member of the TSP (Time Stretched Pulse). FVN has a unique feature that other TSP members do not. It is a high degree of design freedom that makes the proposed method possible without introducing extra equipment. We introduce two useful cases using two and four orthogonal sequences and illustrates their use using simulations and acoustic measurement examples. We developed an interactive and realtime acoustic analysis tool based on the proposed method. We made it available in an open-source repository. The proposed response analysis method is general and applies to other fields, such as auditory-feedback research and assessment of sound recording and coding.
