We plan to develop and integrate three complementary novel technologies and demonstrate their application to noise and vibration cancellation. They are: a novel highly responsive, audio bandwidth combined sensor/actuator and associated "local echo canceller" for both sensing the noise and simultaneously cancelling it; novel moulded composite panels with tailorable characteristics for passive noise damping; advanced digital adaptive control algorithms. The resulting "smart panels" have potential for further added-value functionality upgrades. We will build on a previous TSB-funded project which developed the component technologies to proof-of-principle. We will reduce the size, weight and cost of our sensor/actuator and integrate it into panels; demonstrate operation of our local echo canceller; develop and demonstrate a novel real-time adaptive digital control loop; develop the panels to maximise both passive and active noise damping and to facilitate panel jointing; and demonstrate end-user applications. The growing business opportunity for "smart panels" is driven by two factors: increased awareness of the adverse effects of noise on health (reflected by increasingly stringent legislation and government policy) and the growing desire for a quieter living, working and travelling environment. Applications include buildings, cars (especially the growing number of small luxury vehicles) buses, trains, trams, boats and aircraft. In addition to product sales, IP licensing, design consultancy and firmware / functionality upgrades offer ongoing high-value revenue potential.

我们计划开发和整合三种互补的新技术，并展示它们在消除噪音和振动方面的应用。它们分别是：一种新型的高响应、音频带宽组合的传感器/致动器和相关的“本地回声消除器”，用于感测噪声并同时消除噪声;具有用于被动噪声阻尼的可定制特性的新型模制复合板;先进的数字自适应控制算法。由此产生的“智能面板”具有进一步增值功能升级的潜力。我们将建立在以前TSB资助的项目上，该项目开发了原理验证的组件技术。我们将减少传感器/致动器的尺寸、重量和成本，并将其集成到面板中;演示本地回声消除器的操作;开发和演示新型实时自适应数字控制回路;开发面板以最大限度地减少被动和主动噪声阻尼，并促进面板连接;并演示最终用户应用。“智能面板”的商业机会不断增长是由两个因素驱动的：对噪音对健康的不利影响的认识不断提高（反映在日益严格的立法和政府政策中）以及对更安静的生活，工作和旅行环境的日益渴望。应用范围包括建筑物、汽车（特别是越来越多的小型豪华车）、公共汽车、火车、电车、船只和飞机。除了产品销售，IP许可，设计咨询和固件/功能升级提供了持续的高价值收入潜力。
