The GRAS 43AG Ear and Cheek Simulator is a unique, multi-faceted and multi-purpose tool that helps you accomplish the job in an effective and efficient manner. We call it the table-top KEMAR as it offers you much of the KEMAR capability in a convenient and portable packaging.
GRAS 43AG 耳廓及面颊模拟器是一款独特、多面、多用途的工具，可帮助您以有效和高效的方式完成工作。 我们将其称为桌面式KEMAR，因为它以便携的包装为您提供了大部分KEMAR功能。
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.
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 43AG is a multi-purpose tool and can for example be used to verify frequency response, distortion, isolation and leakage.
Its versatility means that it can be used for testing of both concha and insert types earphones. It can also be used for headphone and headset testing, both circumaural and supra-aural types. Also, all common types of hearing-aids, and telephone handset can be tested with the 43AG.
它的多功能性意味着它可以用于测试耳机和插入式耳机。 它还可用于不同的耳机测试，包括耳罩式和耳罩式测试。 此外，所有常见类型的助听器和电话听筒都可以使用43AG进行测试。
To make ordering and decision making easier, we have made 43AG available in 7 configurations. Except for a few simple steps, they are fully assembled, calibrated and ready for use.为了简化订购和决策，我们提供了7种配置。 只需几个简单的组装步骤，便可以立刻使用。

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。
Choose one of these configurations if you need to test insert type earphones, or if you want the benefits of the improved collapsability of the new pinna when testing circum- and supra-aural earphones.

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.
