19. Ear & Cheek Simulator - 43AG

43AG is to assist you in all facets of the product development cycle: From R&D testing to the final test and approval of the finished product. As your product is put together, your team needs to ensure that individual changes do not conflict with your overall vision. Much of this validation work can be accomplished at their desks, in real time, making you comfortable and giving you the stamp of approval of the final product.

43AG旨在帮助您完成产品开发周期的不同阶段：从研发测试到最终测试受以及批准成品的阶段。随着您把零部件组成为成品，您的团队需要确保个別零部件的变更不会与整体的愿景发生冲突。 使用43AG能让大部分验证工作都可以在办公桌上实时完成，让您舒适地进行验证工作以及轻松获得最终产品的批准印章。

Additionally, very few manufacturers have their entire production vertically integrated and are therefore highly dependent on the quality delivered by their sub-suppliers. To ensure the quality of the complete product, G.R.A.S. offers a variety of mobile test platforms that can easily be deployed at your supplier and in your own in-coming control department. The 43AG Ear and Cheek Simulator by G.R.A.S. provides that comfort and security: The parts comply to the highest standards: Yours.

此外，很少有制造商将其整个生产垂直整合，因此制造商会高度依赖其子供应商提供的质量。 为了确保完整产品的质量，GRAS 提供各种移动测试平台，可以让您在供应商和您自己的控制部门轻松部署。 GRAS的43AG耳廓及面颊模拟器提供舒适性和安全性：零件符合您的最高标准。

The anthropometric pinna has anatomically shaped concha and ear canal, resulting in Improved fit and repeatability. The outer pinna has improved collapsability. In addition to the traditional push mounting from the outside, the pinna is secured with two screws from the inside. These two screw ensure that the pinna is held firmly in place. Therefore, it seals perfectly against the ear simulator and the cheek plate, and it is therefore possible to mount and dismount DUTs repeatedly without compromising the seal. The outer shape of the anthropometric pinna conforms with ITU-T Type 3.3. Read more about the anthropometric pinna here.

人体测量耳廓具有解剖学上形状的外耳和耳道，从而提高了贴合性和可重复性。 外耳廓具有改善了的可折叠性。 除了从外部进行传统的推入式安装外，耳廓还从内侧用两个螺钉固定。 这两个螺钉确保耳廓牢固地固定到位。 因此，它一完美地密封在耳模拟器和面颊颊板上，因此可以重复地安装和拆卸待测品而不损害其密封性。 人体测量耳廓的外形符合ITU-T 的3.3类。 接这里阅读有关人体测量耳廓的更多信息。

GRAS

The new improved pinna has anatomically shaped concha and ear canal and offers better fit, placement and seal, resulting in improved low frequency testing and better low-noise testing. Also, the more realistic ear canal combined with a more flexible pinna provides greater repeatability in measurements of in-ear, circum-aural or supra-aural headphones. The outer shape of the anthropometric pinna conforms with ITU-T Type 3.3. 

新的改进耳廓具有解剖学上形状的耳廓和耳道，提供更好的贴合，放置和密封，从而改善了低频测试和更好的低噪声测试。 此外，更真实的耳道与更灵活的耳廓相结合，可为耳内，耳环或耳罩式耳机的测量提供更高的可重复性。 人体测量耳廓的外形符合ITU-T 3.3类。
