April 14, 2021. 9.30am (China time)

In this 120 minute online seminar, S&V Samford presents Listen’s Technical Support Manager, Steve Tatarunis, discussing some of the more advanced aspects of microphone testing including:

• Substitution, Equalized Source and Transfer Function sequences in SoundCheck, including how to calibrate for these measurements. This is an expansion of material covered in the ‘basic microphone testing webinar’ and include more details about the sequences and calibration and the trade-offs of each method.
• Advanced measurements including polar plot, phase, self-noise, signal to noise, distortion, active/passive noise rejection
• Open loop microphone testing for voice activated devices such as smart speakers, automotive audio etc.
• Advanced hardware and test configurations for measuring microphone arrays and MEMS devices

There is no charge for this seminar, but registration is required.

在这个120分钟的在线研讨会中，声振环保仪器有限公司以及Listen,Inc.技术支持经理Steve Tatarunis，会与大家探讨麦克风测量进阶的知识, 包括：

• SoundCheck中的对比测试法、均衡音源和传递函数程序，包括如何校准这些测量。 这是“基础麦克风测试网络研讨会”涵盖的内容的扩展，并包括有关程序、校准以及每种方法取舍的详细信息。
• 进阶测量，包括极坐标图、相位、底噪、信噪比、失真，主动/被动噪声抑制
• 对语音激活设备（例如智能扬声器，汽车音频等）的开环麦克风测试
• 语音激活设备的开环麦克风测试（例如智能扬声器，汽车音频等）。
• 用于测量麦克风阵列和MEMS的进阶硬件和测试配置

是次研讨会不收取任何费用，但需要提前注册。
