10 Hz Amplitude Modulated Sounds Induce Short-Term Tinnitus Suppression

10 Hz Amplitude Modulated Sounds Induce Short-Term Tinnitus Suppression

Objectives: Acoustic stimulation or sound therapy is proposed as a main treatment option for chronic subjective tinnitus. To further probe the field of acoustic stimulations for tinnitus therapy, this exploratory study compared 10 Hz amplitude modulated (AM) sounds (two pure tones, noise, music, and frequency modulated (FM) sounds) and unmodulated sounds (pure tone, noise) regarding their tempo...

Neural processing of amplitude-modulated sounds.

Amplitude modulation (AM) is a temporal feature of most natural acoustic signals. A long psychophysical tradition has shown that AM is important in a variety of perceptual tasks, over a range of time scales. Technical possibilities in stimulus synthesis have reinvigorated this field and brought the modulation dimension back into focus. We address the question whether specialized neural mechanis...

Auditory streaming of amplitude-modulated sounds in the songbird forebrain.

Streaming in auditory scene analysis refers to the perceptual grouping of multiple interleaved sounds having similar characteristics while sounds with different characteristics are segregated. In human perception, auditory streaming occurs on the basis of temporal features of sounds such as the rate of amplitude modulation. We present results from multiunit recordings in the auditory forebrain ...

Roles for Coincidence Detection in Coding Amplitude-Modulated Sounds

Many sensory neurons encode temporal information by detecting coincident arrivals of synaptic inputs. In the mammalian auditory brainstem, binaural neurons of the medial superior olive (MSO) are known to act as coincidence detectors, whereas in the lateral superior olive (LSO) roles of coincidence detection have remained unclear. LSO neurons receive excitatory and inhibitory inputs driven by ip...
