  3. 2. Hearing by Bone Conduction. Physical and Physiological Aspects

    Författare :Stefan Stenfelt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Bone conduction as a phenomenon, physically and physiologically, is of vital importance in both the diagnosis of a hearing impairment and the development of bone conduction hearing aids. Understanding hearing by bone conduction is difficult, involving sound transmission by wave motion in a complex geometrical structure of layered bone covered with soft tissue and cartilage, finally received by the highly delicate cochlea.

  4. 3. A Finite Element Model of the Human Head for Simulation of Bone-conducted Sound

    Författare :You Chang; Stefan Stenfelt; Namkeun Kim; Frank Böhnke; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone conduction; finite element model，bone-conduction devices;

    Sammanfattning : Bone conduction is usually understood as the hearing sensation based on the vibrations of the skull bone and surrounding tissues. The fact that vibration of the skull bones can result in a sound percept has been known for a long time. However, it is difficult to give a general definition of BC sound. LÄS MER

  5. 4. Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

    Författare :Sushmit Mishra; Mary Rudner; Stefan Stenfelt; Jerker Rönnberg; Thomas Lunner; Mithell S. Sommers; Linköpings universitet; []
    Nyckelord :Working memory; cognitive spare capacity; updating; inhibition; Arbetsminne; kognitiv reservkapacitet; uppdatering; inhibition;

    Sammanfattning : Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content.

  7. 5. Neural and Cognitive Effects of Hearing Loss on Speech Processing

    Författare :Eline Borch Petersen; Thomas Lunner; Stefan Stenfelt; Jonas Obleser; Edmund Lalor; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing loss; speech processing; electroencephalogram EEG; working memory; cognitive load; hearing aid; Hörselnedsättning; bearbetning av tal; elektroencefalogram EEG; arbetsminne; kognitiv belastning; hörapparat;

    Sammanfattning : Understanding speech in the presence of noise can be difficult, especially when suffering from a hearing loss. This thesis examined behavioural and electrophysiological measures of speech processing with the aim of establishing how they were influenced by hearing loss (internal degradation) and listening condition (external degradation).
