Hearing aid manufacturers strive to optimize their wireless hearing aid offerings both in terms of connection reliability as well as power efficiency. Variance across patients and listening conditions can make optimizing wireless hearing aid systems a complex process.
Factors such as connection distance, proximity of reflective surfaces, interference from other wireless devices, and energy loss through body absorption must all be factored into the hearing aid design. For example, indoor wireless performance may be very different from wireless performance experienced outdoors, where the only reflective surface may be the ground on which the hearing aid user is standing. Furthermore, individual differences in body geometry increase the variability that wireless engineers must account for when designing a system that provides each user with a consistent and reliable experience.
As awareness of wireless hearing technology grows, hearing healthcare professionals may notice an uptick in long-term safety concerns. Consumers should be confident knowing that wireless hearing aids are safe and strictly regulated medical devices that meet governmental wireless communication standards in addition to those set forth for medical devices.

If the trough temperature is high when stratified, up to 8? 12?, 70? 90d can be sown. You can also mix the seeds and sand and put them into a wooden box and other windows to put them in the vegetable cell for layering. The schisandra seed layering should be based on the sowing date to determine the temperature and time so that the radicles after stratification will not break through the seed coat. Planting the field at a low temperature cannot sow the plant and cause losses. The seeds of Schizandra chinensis in the low-temperature wet sand layering area can be matured in a short time. During the middle and late stratification, the endogenous antiseptic activity of seeds of Schisandra chinensis was reduced through the low-temperature stratification area, and seed germination was promoted.
Schisandra seed treatment method
After harvesting mature fruits of Schisandra chinensis, select the full-grained, grainy, and disease-free fruits of Schisandra chinensis, soak it in warm water (40-45°C) for 3 days, remove the flesh, select the seeds, and then remove the grains by water selection. In a dry and ventilated place, dry and laminate. The stratification treatment method is to fully mix the prepared seeds with 3 times the mass of wet sand. The humidity of the sand is determined by hand-squeezing. The pits of 60cm60cm60cm are excavated, the thickness of the mixture of seeds and sand is 40cm, the soil is 15cm, and a layer is covered. Grass, with soil pressure, dig around the drainage ditch, prevent rainwater poured into. During this process, regular checks were made to prevent seed from becoming moldy. If any mold colonies were found to produce 1000 times the available chlorothalonil solution or spray treatment with thiophanate-methyl 1000-fold solution. General stratification treatment 90 ~ 120 days, see the radicle can be sown slightly exposed.
