Evolving tools and techniques in response to electrification and modern testing demands

In the dynamic world of automotive engineering, acoustic testing is rapidly evolving—especially with the shift toward electric vehicles (EVs). As noise sources change and test environments become more complex, the demand for precision, durability, and smarter tools is reshaping the field. In this two-part series, we explore the latest developments in automotive acoustic measurement technology.

Axiometrix Solutions 通过其全球知名品牌 Audio Precision、GRAS Sound & Vibration 和 imc Test & Measurement 提供尖端的测试和测量解决方案。这三大品牌在 Axiometrix Solutions 的统一技术平台下协同运作，为汽车测试需求提供一站式解决方案，帮助制造商和工程师避免因系统分散和供应商管理而产生的成本和复杂性。

研究表明，长期暴露于噪音环境会降低生活质量，引发压力、睡眠障碍及效率下降。因此，消费者要求更安静的家居环境，期望高性能产品在保持效率的同时减少背景噪音。这促使制造商将降噪作为家电设计的重点。然而，满足这一需求对产品开发工程师提出了挑战，尤其是需在噪音控制与其他性能指标间取得平衡。

In-ear headphones are a daily essential for millions, but ensuring top-tier sound quality is more complex than it seems. Beyond frequency response, ear canal geometry significantly impacts how sound is measured and experienced. Insights from the GRAS Sound & Vibration whitepaper, The Impact of Ear Canal Geometry on In-Ear Headphone Testing, reveal how ear simulators and ear canal variations affect audio quality.

电动汽车（EV）的日益普及和多样化选择，标志着汽车行业向可持续性和创新方向的重大转变。然而，这一转型也为车辆设计带来了新的挑战，尤其是在车内声学方面。随着内燃机嗡嗡声的消失，人们将注意力转向了最大限度地减少其他噪声源，其中风噪声成为主要关注点。这使得风噪声测试变得越来越重要，而风洞测试等复杂技术也从昂贵的奢侈品变成了昂贵的必需品——这意味着工程师们需要快速、准确地完成测量。
