![]() You hear things like "digital volume control is perfect because it is done in 32 bit" which is true in some aspects but not others. I agree that it was hard for me to wrap my head around the various volume control issues. ![]() If done right it should be the best possible solution for digital audio.Įarly in the digital age when it was not possible to upsample the signal it was for sure a limitation. Just like most other components or speakers. Sure, there are not always a digital volume does all things as it should. Without any signal just go from low to max gain and listen if you hear any change of noise. If you have a DAC or some other source with digital volume go close to the speakers. ![]() That way there will not be any noise when you lower the volume. This should be done in software on a computer or from the hardware itself. The way to solve the signal to noise problem with 16bit audio using a digital volume is to upsample the signal to 24 or 32-bit so you have a huge amount of headroom. It is not that the music will be distorted or unclear. To explain signal to noise we are talking about dynamic range. When you lower the volume on any passive volume control, digital or analogue the signal to noise ratio will go down and introduce noise. In many situations 2V is not enough to play real loud and you would need active preamp. That is 6db more and should be plenty for any setup. That will be max possible gain or volume (volume or gain is the same thing).įor XLR it is 4V. If you are using a passive or digital volume control you will have the voltage that come inn to work with. I still kind of understand it and can try to describe it in a way normal people can understand. Of course your effective SNR will still be limited by the analog noise floor.Ĭlick to expand.I agree. In contrast to a digital volume control an analog volume control will attenuate both signal and noise, preserving the signal to noise ratio as you attenuate. This is an area where it pays to have a DAC with high SNR so you can ensure a low noise floor. ![]() However in practice if you cannot hear any noise from your listening position with nothing playing then attenuating really doesn't lose anything as your ambient noise floor is higher than your system noise floor. This means that when you attenuate you are effectively reducing your signal to noise ratio. The second issue is that a digital volume control only attenuates the signal and does not attenuate noise. With digital volume control there are two issues to worry about, these will be the same whether you are using digital volume control implemented on a DAC chip or software volume control.įirst issue is quantization noise, in practice this is rarely an issue these days as volume calculations are typically done at 24 bit or better so you can attenuate 16 bit data by 48 dB before you even have the possibility of an issue. ![]()

![]() ![]() Transpulmonary pressures of more than 60 to 70 mmHg can cause an alveolar rupture. Pulmonary barotrauma occurs when the pressures in a person’s lungs are unequal to the ambient environmental pressures, going beyond the limits of the lungs. ![]() The lungs are most adversely affected by declines in lung capacity in the first 10 meters (32.8 ft) with a 50% reduction. At 40 meters (131.2 ft), water pressure will be 5 ATA, and air pressure will exert a force of 73.5 lbs/in, causing a decrease in lung capacity by 80%. At 30 meters (98.4 ft), water pressure will be 4 ATA, and air pressure will exert a force of 58.8 lbs/in, causing a decrease in lung capacity by 75%. At 20 meters (65.6 ft), water pressure will be 3 ATA, and air pressure will exert a force of 44.1 lbs/in, causing a decrease in lung capacity by 67%. At 10 meters (32.8 ft), water pressure will be 2 ATA, and air pressure will exert a force of 29.4 lbs/in, causing a decrease in lung capacity by 50%. For every 10 meters (32.8 ft) of depth into the sea, the water pressure will increase by 1 ATA. At sea level (0 meters, 0 ft), the air pressure exerts a force of 14.7 lbs/in or 1 atmosphere absolute (1 ATA). Plainly stated, as pressure increases on the descent, the volume must decrease, and as pressure falls on the ascent, the volume must increase. Complications include local infiltration of gas into the damaged tissue or local circulation interfering with organ function or resulting in circulatory compromise.Īccording to Boyle’s law, which states that at a constant temperature, a volume of a gas varies inversely with the pressure to which it is subjected, P1V1= P2V2. Damage occurs due to over tension or shear forces from the expansion of the gas within or by pressure hydrostatically transmitted through the tissues. Barotrauma is an injury inflicted by a difference in pressure between a gas inside or outside the body and the pressure of the surrounding gas or fluid. Pulmonary barotrauma most often occurs during ascent and is due to lung overexpansion when a SCUBA diver returns to the surface without exhaling or when the air becomes trapped in the lung. It can happen during descent (negative pulmonary barotrauma or lung squeeze) or during ascent (positive pulmonary barotrauma is also known as pulmonary overinflation syndrome (POIS). ![]() Pulmonary barotrauma can occur during self-contained underwater breathing apparatus (SCUBA) diving or free diving. Pulmonary barotrauma is a potential diving injury. The workers would often have intense back pain that left them bent over, which is how caisson disease earned the nickname "the bends." This was due to their being rested at the start of the shift compared to being exhausted when the workday was through. The caisson workers often said that they felt well while working. These symptoms included dizzy spells, difficulty breathing, and sharp pain in the abdomen or joints. Symptoms of caisson disease were observed among bridge workers after finishing their shifts underwater and coming back to the surface. Diving as a profession can be dated back to more than 5000 years, yet diving-related diseases were not described until Paul Bert wrote about caisson disease in 1878. Many people dive for recreation, competitive sport, commercial employment, and military training. It is enjoyed by novices and professionals alike. Known triggers of urticaria should be avoided.Diving in open waters is popular. Doxepin, calcium channel blockers, or immunosuppresive drugs may be needed for symptoms that are not well controlled with antihistamines. Patients should avoid identified allergens. The use of both H 1 and H 2 receptor blockers has been recommended but has not been proven more effective. Treatmentĭrugs that block histamine-1 (H 1) receptors (antihistamines) are the primary treatment for urticaria. Angioedema is frequently associated with urticaria. ![]() It affects people of all ages but is most common between the ages 20 and 40. Urticaria is a primary sign of local and systemic anaphylactic reactions. The mast cell degranulation is due to an immunoglobulin E–mediated reaction to allergens (e.g., foods, drugs, or drug additives), heat, cold, and, rarely, infections or emotions. Urticaria is caused by vasodilation and increased permeability of capillaries of the skin due to the release by mast cells of vasoactive mediators. Synonym: hives See: illustration allergy angioedema Etiology The wheals appear primarily on the chest, back, extremities, face, or scalp. An allergic reaction marked by multiple discrete swellings on the skin (wheals) that are intensely itchy and last up to 24 hr. ![]() ![]() ![]() ‘South Side’ moved to HBO Max for the second season and is now categorized as an original series by the streamer.

![]() ![]() My husband and I recently decided to return to Hawaii for our ten year wedding anniversary, but this time to the Island of Hawaii, and instead of the big luxury hotel we opted for a more relaxed and low-key B & B. And I'm glad to be reviewer #100, for what it's worth! And although I laughed off the lava showers before - I went there at least once, if not twice a day. We stayed in the cottage which was great, it gave us a bit more privacy, though it lacks the ocean view most of the other rooms have, but which we didn't miss. Smoothies, warm dishes, jam made from local fruit. We had the added benefit of his mom, Kathy, visiting - she is awesome, the friendliest lady that always had something nice to say at the beginning of the day.

Add a bottle of wine, and it makes for the best evening at least we could imagine. The lanai is wonderful, aside from the breakfast we also had all dinners here, just putting some fish on the BBQ, or eating Poke or sashimi picked up at one of the local stores. The grounds are somewhere between manicured and being a working plantation, where they grow coffee as well as a number of fruit, which we enjoyed for breakfast. The premises: It's an old grand house, and Greg and Michael redid it beautifully. It's at about 1500 feet, and is less hot than most other places you stay at at the Big Island or in Hawai'i. It's overlooking the Kealakekua Bay, and the coast to the south. Where do I start: The location: It's away from touristy Ali'i drive, and far away from the mega resorts in the north. I'd give the Ka'awa Loa Plantation 10 stars if I could, we stayed for a week and it was perfect in every aspect. ![]() ![]() You get updated specs and the same great range of family-friendly features, including some particularly helpful parental controls and full Alexa support. ![]() This 7th-generation Fire HD 10 is fresh for 2017, replacing the 10-inch tablet from last year.
