概括
放大双耳听觉线索可以提高噪音中的语音理解. 然而,这种技术并不能显著地提高掩盖的空间释放,特别是对于已经熟练的空间听力倾听者.
科学领域:
- 听觉神经科学
- 声信号处理
- 人类的感知
背景情况:
- 双耳助听器在杂的环境中进行有效的沟通.
- 声间暗示放大提高了语音可理解性,但也可能导致文物.
- 放大个体头部相关传递函数 (HRTF) 的感知效应尚不清楚.
研究的目的:
- 对个别HRTF应用的声间暗示放大进行研究.
- 减少与放大方法相关的空间扭曲.
- 评估掩盖对语音可理解性和空间释放的影响.
主要方法:
- 重新检查和修改之前的耳间暗示放大方法.
- 对个别的HRTF进行放大.
- 使用听觉模型和听力测试 (语音对语音掩盖) 进行评估.
主要成果:
- 放大语音间的阶段和水平差异可以提高语音可理解性.
- 在行为上没有观察到掩盖空间释放 (SRM) 的显著增强.
- 听觉模型预测了比行为结果更大的SRM收益.
结论:
- 声间暗示放大对语音可理解性有好处,但对SRM的好处有限.
- 听众对个别空间线索的熟悉可能会影响感知到的好处.
- 对于具有强大的SRM能力的听众来说,好处会减少.

Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Masking and Demasking Agents
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

Muscles that Move the Head
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain.

Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
