    • The present disclosure relates to a method for obtaining a correct placement of an in-ear communication device, such as a hearing aid, in the ear canal of a user, where the method comprises the steps of providing an in-ear communication device comprising a probe sound generator configured to emit a probe sound from the device into the ear canal, where the level of the probe sound can be adjusted by the user and providing a vocalization sound generator. In a first stage: (i) placing the in-ear communication device in the ear canal thereby forming a substantial acoustic seal in the soft part of the ear canal; (ii) by means of said vocalization sound generator generate a vocalization sound; (iii) emitting a probe sound from the device into the cavity of the ear canal formed between the device and the ear drum, the probe sound having a level that makes it audible in the presence of the vocalization sound; (iv) the user adjusting the level of the probe sound such that it is just below the masking threshold of the vocalization sound. In a second stage: (v) reducing the level of the probe sound below the masking threshold determined in the first stage; (vi) by means of said vocalization sound generator generate substantially the same vocalization sound as in the first stage; (vii) gradually inserting the device deeper into the ear canal in the direction towards the ear drum, until a position in which the probe tone is no longer masked by the vocalization sound, i.e. where the probe sound becomes audible in the presence of the vocalization sound; and (viii) maintaining the device in this position in the ear canal, this position being the correct position of the device in the ear canal. The disclosure further related to in-ear devices configured to be used in the method according to the disclosure.
    • 本公开涉及一种用于获得一种入耳式通信装置的正确放置的方法,测试了作为用户,其中该方法包括提供在耳,其包括通信装置的步骤的耳道中的助听器 测试声音发生器被配置为发射从所述设备的测试声音进入耳道,其中测试声音的声级可以由用户和提供的发声声音发生器进行调整。 在第一阶段中:(i)将所述的耳内的通信设备在耳道中,从而形成在耳道的软的部分相当的声密封; (ii)通过发声的装置,把所述声音发生器产生一个发声的声音; (三)从发光装置中的测试声音到装置和鼓膜之间形成的耳道的腔中,具有电平做了声音样本使得它在发声声音的存在可听; (iv)所述用户调节所述测试声音搜索的电平做了它刚好低于发声的声音的掩蔽阈值。 在第二阶段中:(v)的减少低于在第一阶段试验开采的掩蔽阈值的确定性的声音的电平; (六)借助于所述发声声音发生器产生基本上相同的发声声音作为在第一阶段; (七)逐步将所述装置深入朝鼓膜的方向上的耳道,直到一个位置,其中测试音调由声发声不再掩蔽,即 其中样品声音变得在发声声音的存在可听; 和(viii)中保持在耳道中此位置的装置,该位置是所述设备在耳道中的正确位置。 本发明还涉及配置成在所述方法雅丁本发明中使用的耳内的设备。
