Cortical potentials evoked by tone frequency changes can predict speech perception in noise [0.03%]
由音调频率变化诱发的皮层电位可以预测噪声中的言语感知能力
Bernard M D Vonck,Jan A A van Heteren,Marc J W Lammers et al.
Bernard M D Vonck et al.
Accurate and objective assessment of higher order auditory processing is challenging and mainly relies on evaluations that require a subjects' active participation in tests such as frequency discrimination or speech perception in noise. Thi...
Intracochlear pressure in cadaver heads under bone conduction and intracranial fluid stimulation [0.03%]

Background: The frequency dependent contributions of the various bone conduction pathways are poorly understood, especially the fluid pathway. The aim of this work is to measure and investigate sound pressure propagation ...
Which threshold do we trust? A comparison of threshold measurements in adult bone-conduction device users and normal hearing adults [0.03%]
可信赖的阈值是多少？成人骨传导装置佩戴者和正常听力成人阈值测定比较研究

In-air and underwater audiograms and directional hearing abilities were measured in humans. The lowest underwater thresholds were 2.8 µW/m2 or 3.6 mPa at a frequency of 500 Hz. The underwater hearing thresholds were 4-26 dB and 40-62 dB hi...
Age-related changes in neuronal receptive fields of primary auditory cortex in frequency, amplitude, and temporal domains [0.03%]
老龄小鼠初级听皮层神经元的频率、振幅和时序感受野变化规律

Aging populations often experience difficulties hearing. This phenomenon, known as age-related hearing loss, is associated with decreases in hearing sensitivity and pathophysiological changes in the central auditory system, including the pr...
Clinical perspective on hearing preservation in cochlear implantation, the University of Iowa experience [0.03%]
人工耳蜗手术听力保存的临床体会——爱荷华大学的经验报告

Preservation of residual acoustic hearing has emerged as an important concept for those individuals undergoing cochlear implantation with residual low frequency hearing. Acoustic plus electric speech processing improves hearing outcomes in ...
Auditory filter shapes derived from forward and simultaneous masking at low frequencies: Implications for human cochlear tuning [0.03%]
用人耳低频向前掩蔽和同时掩蔽数据推测人耳耳蜗调谐特性
John Leschke,Gerardo Rodriguez Orellana,Christopher A Shera et al.
John Leschke et al.
Behavioral forward-masking thresholds with a spectrally notched-noise masker and a fixed low-level probe tone have been shown to provide accurate estimates of cochlear tuning. Estimates using simultaneous masking are similar but generally b...
The effect of stimulus level on excitation patterns of individual electrode contacts in cochlear implants [0.03%]
刺激强度对耳蜗植入电极接触点激发模式的影响研究

Jan Dirk Biesheuvel et al.
Objective: Spread of excitation (SOE) in cochlear implants (CI) is a measure linked to the specificity of the electrode-neuron interface. The SOE can be estimated objectively by electrically evoked compound action potenti...
Carbamazepine induces upward frequency shifts of spontaneous otoacoustic emissions [0.03%]
卡马西平诱导自发性耳声发射向高频偏移
Emile de Kleine,Bert Maat,Jan D Metzemaekers et al.
Emile de Kleine et al.
In three subjects, we measured spontaneous otoacoustic emissions (SOAEs) when they were using carbamazepine (CBZ), and compared this to the SOAE measurement when they were not using CBZ. We observed 14 SOAEs showing a consistent upward shif...
Cortical auditory evoked potentials, brain signal variability and cognition as biomarkers to detect the presence of chronic tinnitus [0.03%]
皮层听觉诱发电位、脑信号变异和认知作为检测慢性耳鸣存在的生物标志物
Emilie Cardon,Hanne Vermeersch,Iris Joossen et al.
Emilie Cardon et al.
The current limited understanding of tinnitus neurophysiology is one of the major obstacles in developing effective treatments for chronic tinnitus. As such, there is an urgent need for knowledge on underlying neural and/or neurobehavioral ...
