Tinnitus Treatment Toronto

If you have experienced a ringing sound in your ear or hear sounds that others don’t detect, you may be suffering from tinnitus. Fortunately, there are many tinnitus treatment Toronto that can relieve or eliminate some or all of your symptoms. What are some of these options?

Get Your Mind Off of the Ringing Sounds

One common tinnitus treatment Toronto option is to engage in relaxation or cognitive therapy. This will literally shift your attention away from the ringing and toward something that is more soothing. For instance, you may teach yourself to believe that you are on a beach or getting a massage. Getting your mind to think about something positive can help you to forget about the ringing even if it doesn’t go away. You may find that it is now easier to go to sleep or get through the day without the constant noise bothering you.

Use Music and Other Sounds to Retrain Your Ear

Tinnitus may be caused by an imbalance in the ear that may be corrected through sound training. Sound training involves playing music to teach the brain and your ear to only hear sounds that exist as opposed to the ringing that you currently hear. Over time, it may help solve the root cause of your problem and get rid of the tinnitus as well as the symptoms that you experience. Even if it doesn’t go away completely, you may find that your quality of life improves after such treatment.

Medication May be Worthwhile to Temporarily Treat Your Tinnitus Symptoms

The use of antidepressants can help you get past the depression that you may feel because of the constant ringing. As tinnitus can cause you to have trouble sleeping, you could become listless, agitated and angry. Over time, you may begin to withdraw from society, stop doing the things that you used to enjoy and show other signs of clinical depression. You should talk to your doctor before going on a prescription drug as a form of tinnitus treatment Toronto.

Tinnitus can be a debilitating condition if you don’t know where to get help for it. Generally, only you can hear the ringing in your ear, which may make it hard for others to understand why you may be acting strangely in certain situations. Your doctor may be able to help prescribe medication or refer you to a specialist for advanced treatment options.

A Novel ENU-Induced Mutation in Myo6 Causes Vestibular Dysfunction and Deafness

by Elaine Y. M. Wong, Chelsea Y. Xu, Manisha Brahmachary, Pin-Xian Xu

Mouse N-ethyl-N-nitrosourea (ENU) mutagenesis has generated many useful animal models for human diseases. Here we describe the identification of a novel ENU-induced mouse mutant strain Turner (Tur) that displays circling and headtossing behavior and progressive hearing loss. Tur/Tur homozygous animals lack Preyer and righting reflexes and display severe headtossing and reaching response defect. We mapped the Tur mutation to a critical region of 11 cM on chromosome 9 that includes myosin VI. Direct sequence analysis revealed a c.820A>T substitution in exon 8 of the Myo6 gene that changes amino acid Asn200 to Ile (p.N200I) in the motor domain. Analysis of inner ear hair cells by immunohistochemistry, scanning electron microscopy and histology revealed degeneration of hair cells in the inner ear and structural malformation of the stereocilia in the cochlea of Turner homozygous mutant mice. Our data indicate that this novel mouse strain provides a useful model for future studies on the function of myosin VI in mammalian auditory and non-auditory systems and in human syndromes.

Elastic parabolic equation and normal mode solutions for seismo-acoustic propagation in underwater environments with ice covers

cm_sbs_024_plain.png

Sound propagation predictions for ice-covered ocean acoustic environments do not match observational data: received levels in nature are less than expected, suggesting that the effects of the ice are substantial. Effects due to elasticity in overlying ice can be significant enough that low-shear approximations, such as effective complex density treatments, may not be appropriate. Building on recent elastic seafloor modeling developments, a range-dependent parabolic equationsolution that treats the ice as an elastic medium is presented. The solution is benchmarked against a derived elasticnormal modesolution for range-independent underwater acoustic propagation. Results from both solutions accurately predict plate flexural modes that propagate in the ice layer, as well as Scholte interface waves that propagate at the boundary between the water and the seafloor. The parabolic equationsolution is used to model a scenario with range-dependent ice thickness and a water sound speed profile similar to those observed during the 2009 Ice Exercise (ICEX) in the Beaufort Sea.

Observations and Bayesian location methodology of transient acoustic signals (likely blue whales) in the Indian Ocean, using a hydrophone triplet

cm_sbs_024_plain.png

A notable sequence of calls was encountered, spanning several days in January 2003, in the central part of the Indian Ocean on a hydrophone triplet recording acoustic data at a 250 Hz sampling rate. This paper presents signal processing methods applied to the waveform data to detect, group, extract amplitude and bearing estimates for the recorded signals. An approximate location for the source of the sequence of calls is inferred from extracting the features from the waveform. As the source approaches the hydrophone triplet, the source level (SL) of the calls is estimated at 187 ± 6 dB re: 1 μPa-1 m in the 15–60 Hz frequency range. The calls are attributed to a subgroup of blue whales, Balaenoptera musculus, with a characteristic acoustic signature. A Bayesian location method using probabilistic models for bearing and amplitude is demonstrated on the calls sequence. The method is applied to the case of detection at a single triad of hydrophones and results in a probability distribution map for the origin of the calls. It can be extended to detections at multiple triads and because of the Bayesian formulation, additional modeling complexity can be built-in as needed.

Comparisons between physics-based, engineering, and statistical learning models for outdoor sound propagationa)

Many outdoor sound propagationmodels exist, ranging from highly complex physics-based simulations to simplified engineering calculations, and more recently, highly flexible statistical learning methods. Several engineering and statistical learningmodels are evaluated by using a particular physics-based model, namely, a Crank-Nicholson parabolic equation (CNPE), as a benchmark. Narrowband transmission loss values predicted with the CNPE, based upon a simulated data set of meteorological, boundary, and source conditions, act as simulated observations. In the simulated data set sound propagation conditions span from downward refracting to upward refracting, for acoustically hard and soft boundaries, and low frequencies. Engineering models used in the comparisons include the ISO 9613-2 method, Harmonoise, and Nord2000 propagation models. Statistical learning methods used in the comparisons include bagged decision tree regression, random forest regression, boosting regression, and artificial neural network models. Computed skill scores are relative to sound propagation in a homogeneous atmosphere over a rigid ground. Overall skill scores for the engineering noise models are 0.6%, −7.1%, and 83.8% for the ISO 9613-2, Harmonoise, and Nord2000 models, respectively. Overall skill scores for the statistical learningmodels are 99.5%, 99.5%, 99.6%, and 99.6% for bagged decision tree, random forest, boosting, and artificial neural network regression models, respectively.

Analysis of coupled fast-shear and extensional vibrations of a LiTaO3 crystal plate with a ferroelectric inversion layer

cm_sbs_024_plain.png

The resonance vibrations of LiTaO3 fast-shear overtone mode resonators with a ferroelectric inversion layer are analyzed. In addition to the fast-shear mode, the coupled extensional mode is considered. Different from most of the LiTaO3resonators studied in the literature that are based on the slow-shear mode, the resonator in this paper operates with the fast-shear overtone mode. Results show that the capacitance ratio assumes maxima at two resonances, which are identified to be the second overtone modes of fast-shear and extension, respectively. It is found that the thickness of the inversion layer has obvious influences on the capacitance ratio of fast-shear and extensional modes. This condition may provide a simple method to adjust capacitance ratios of piezoelectricresonators. The influence mechanisms are also discussed. Besides, the effect of the cut angle of the crystal on the mode shape of vibrations is also investigated. The results can be used as important basis of parameters designs of LiTaO3resonators operating on the fast-shear overtone mode.
