Promoting High Value, Patient-Centric Care with Alternative and Complementary Devices

Today, I want to talk about some industry challenges and opportunities that are in front us as they relate to changes in the marketplace with the aging population and the influx of baby boomers. We will talk about some alternative and complementary devices, one of which is Hypersound, and why and how that might be a viable treatment option for patients.

Cure Tinnitus By Meditating

If you suffer from tinnitus, you may go to great lengths to find a cure. Many people will unfortunately try everything from ear drops to surgery in an effort to ease the symptoms. Tinnitus may be characterized by a ringing, hissing, tingling or other sound in the ears, and it may be loud, soft, constant or intermittent. In many cases, the sound is most noticeable when there is minimal background noise, such as when you are trying to fall asleep, reading a book or working in a quiet office. This is a condition that can have a truly negative impact on your quality of life, and you may be wondering if you can cure tinnitus by meditating.

Why Choose Meditation as a Treatment
Meditation is a holistic form of therapy that is effective for many people who have tinnitus. You should be aware that you cannot cure tinnitus by meditating, but you may be able to reduce the suffering that you experience because of the condition. When you have tinnitus, your mind may be focused on the sound, and this can make it difficult to focus on anything else. Through meditation, you focus your brain on relaxing, and this can help you to tune out the noise more easily. Altogether, meditation can help you to live more comfortably with the condition while you try to find a cure.

Finding an Effective Cure for Tinnitus
There are different cures available for tinnitus, but meditation is not one of them. The cure that may work for you will be dependent on the cause of the condition. For example, if tinnitus is caused by a blockage in the ear, removing the blockage and applying medicated ear drops for several days or weeks may work well. If there is actual cochlear damage to the inner ear, surgery may be necessary as a cure. Some people also respond well to tonal therapy for tinnitus, and this is a holistic, non-medicated solution that some will try before scheduling surgery.

Many who have this condition want to know if you can cure tinnitus by meditating, and it is understandable that you would want to try anything you can to alleviate your bothersome symptoms. Meditation can alleviate symptoms, but it will not cure tinnitus. You may consider using meditation while searching for an effective cure. This can improve your quality of life while you work to overcome this issue.

Sine-wave and noise-vocoded sine-wave speech in a tone language: Acoustic details matter

Sine-wave speech (SWS) is a highly simplified version of speech consisting only of frequency- and amplitude-modulated sinusoids representing the formants. That listeners can successfully understand SWS has led to claims that speech perception must be based on abstract properties of the stimuli far removed from their specific acoustic form. Here it is shown, in bilingual Cantonese/English listeners, that performance with Cantonese SWS is improved by noise vocoding, with no effect on English SWS utterances. This manipulation preserves the abstract informational structure in the signals but changes its surface form. The differential effects of noise vocoding likely arise from the fact that Cantonese is a tonal language and hence more reliant on fundamental frequency (F0) contours for its intelligibility. SWS does not preserve tonal information from the original speech but does have false tonal information signalled by the lowest frequency sinusoid. Noise vocoding SWS appears to minimise the tonal percept, which thus interferes less in the perception of Cantonese. It has no effect in English, which is minimally reliant on F0 variations for intelligibility. Therefore it is not only the informational structure of a sound that is important but also how its acoustic detail interacts with the phonological structure of a given language.

Ventriloquism effect with sound stimuli varying in both azimuth and elevation

When presented with a spatially discordant auditory-visual stimulus, subjects sometimes perceive the sound and the visual stimuli as coming from the same location. Such a phenomenon is often referred to as perceptual fusion or ventriloquism, as it evokes the illusion created by a ventriloquist when his voice seems to emanate from his puppet rather than from his mouth. While this effect has been extensively examined in the horizontal plane and to a lesser extent in distance, few psychoacoustic studies have focused on elevation. In the present experiment, sequences of a man talking were presented to subjects. His voice could be reproduced on different loudspeakers, which created disparities in both azimuth and elevation between the sound and the visual stimuli. For each presentation, subjects had to indicate whether the voice seemed to emanate from the mouth of the actor or not. Results showed that ventriloquism could be observed with larger audiovisual disparities in elevation than in azimuth.

Orthogonal matching pursuit applied to the deconvolution approach for the mapping of acoustic sources inverse problem

Microphone arrays and beamforming have become a standard method to localize aeroacousticsources.Deconvolution techniques have been developed to improve spatial resolution of beamforming maps. The deconvolution approach for the mapping of acoustic sources (DAMAS) is a standard deconvolution technique, which has been enhanced via a sparsity approach called sparsity constrained deconvolution approach for the mapping of acoustic sources (SC-DAMAS). In this paper, the DAMAS inverse problem is solved using the orthogonal matching pursuit (OMP) and compared with beamforming and SC-DAMAS. The resulting noisesource maps show that OMP-DAMAS is an efficient source localization technique in the case of uncorrelated or correlated acoustic sources. Moreover, the computation time is clearly reduced as compared to SC-DAMAS.
