Infant sleep machines designed to soothe baby with sound are popular with harried parents, but they could end up harming babies' hearing, according to a new study. Researchers tested 14 widely available machines that play white noise and other soothing sounds for an article published Monday in the journal Pediatrics. And those sound limits may be too liberal for infants, whose ears differ from adults', says Papsin. The study only looked at the potential for harm: No one knows how parents actually use these machines, and there have been no hearing studies of infants exposed to them. But the researchers recommend that parents play the machines as quietly as possible, as far from the baby as possible, and for as short a time as possible. The researchers recommend that manufactures lower the maximum volume, include automatic timers to shut off the devices and insert printed warnings about noise-induced hearing loss.
The researchers did not reveal the names of the tested machines, and several individual manufactures declined to comment.

Researchers are warning that infant noise machines, when played continuously at maximum volume, may harm babies' hearing.
White noise machines may help babies sleep more soundly, but they may also damage their delicate ears, a group of researchers warned. Some widely available brands of infant sleep machines a€” which, like ambient noise machines for adults, emit a variety of soothing sounds designed to block out external noise a€” are capable of playing at volumes that could impair an infant's hearing, according to a study published March 3 in the journal Pediatrics. Researchers tested 14 of the devices and found that when played at maximum volume for an extended period, placed at either 1 foot or 3 feet from a crib, the noise machines exceed the decibel limits recommended for hospital nurseries. Like ambient noise machines for adults, infant noise machines play soothing sounds such as ocean waves or raindrops.
Those limits are in place in order to protect babies' hearing and auditory development, said Dr.
Even at 6.5 feet away, all but one of the devices a€” which were not specified by brand in the study a€” surpassed the hospital limits. Manufacturers should be required to put warnings on the products, limit the volume capabilities and include timers, study authors advised. And if parents wish to use the machines, they should place them as far away from the crib as possible, keep the volume low and limit the time the devices are left turned on.

OSHA 1910.134 Training Packets, NIOSH 42CFR84 product support and application training are available. BurnFree Burn Care Kits come in various sizes to meet the requirements of industry, food service, emergency services and personal use.
BurnFree Blankets provide immediate physical protection as well as smoke and heat shielding protection from fire. The world's first standardized and calibrated "full body protective filtration garment" to protect against heat build up and dangerous noxious particles.
Calibrated for > 99%+ retention of 0.3 micron particles with an efficiency similar to an N95 respirator. The first material to offer a filtration rating similar to particulate style respirators 95+. Body Filter 95+ incorporates the highest quality in electrostatically charged filter media into a superior filtration system. Utilizes state-of-the-art lamination technology to combine a soft non-woven fabric with micro porous film.
CHEMSPLASH™ has been tested for penetration resistance by exposure under pressure to the following list of hazardous chemicals (ASTM 1001) in accordance with ASTM Test Method 903. CHEMSPLASH™ combines the economy of microporous technology with a revolutionary process of creating a surface augmented with a micro membrane over the pores. CHEMSPLASH™ is the first protective material to incorporate barrier resistance to penetration by dangerous chemicals for incidental and accidental chemical splash while providing continuous outward moisture vapor transmission to minimize the potential for heat stress. CHEMSPLASH™ is created by a proprietary process (patent pending) where a new monolithic membrane is created on top of the pores of the microporous membrane which services as a base for the new Miro-Monolithic Hybrid Membrane. The fabric and garment is not for use with some chemicals and hazardous agents and it is the user's responsibility to determine the level of risk and the proper personal protection needed.
PyroGuard™ FR garments are made with a tough, breathable, light weight, and cloth-like material with a base fabric of hydro entangled wood pulp and polyester topically treated with a phosphate-based flame retardant chemical. Polypropylene is a lightweight, breathable fabric that provides economical protection for various work environments.
At one foot away, three of the machines produced such intense sound levels at maximum volume that, if played through the night, they would exceed allowable noise limits for adults at work. Blake Papsin, the lead researcher and chief otolaryngologist at The Hospital for Sick Children in Toronto, told NBC News. Blake Papsin, otolaryngologist-in-chief at the Hospital for Sick Children in Toronto, explains that infants' ears are more delicate than adults'. And three of the machines when played at maximum levels for 8 hours exceeded legal noise limits for adult workplaces.

Safety and effective for cleaning respirators, hard hat suspensions, and other personal protective equipment. Unlike most polyester gauze products, BurnFree utilizes a unique open-cell foam delivery system that allows gel to completely permeate the dressing. Unlike traditional products, BurnFree's gel does not have lidocaine which makes it suitable for use on small children and avoids potential allergic reactions.
The Body Filter 95+ will provide "keep out" dry particulate protection while providing 125 times more breath-ability than the leading brand.
Exceptional abrasion resistance is provided by a unique aperture molded hard plastic polymer grid on the surface. More than 120 times air flow permeability when compared to the Calendared Polyolefin Fabric.
This technology allows us to offer a fabric with superior liquid barrier, better particulate barrier, stronger tear resistance and lower lint then other fabrics. The result Hybrid Breathable Membrane System is a transformed barrier which retains "breathability" but becomes highly penetration resistant (ASTM 903) to a broad group of dangerous, noxious and poisonous chemicals (ASTM101). This combination of flame retardant chemistry and wood pulp causes the fabric to char at temperatures below the fabric's ignition point. Polypropylene is appropriate for use in non-hazardous work places and is a low-cost solution for non-hazardous dry particulates, dirt and grime. It gets more gel to the wound and allows for better heat absorption and cooling of the burn.*All BurnFree Dressings are sterile. BurnFree Blankets can be used as a body wrap to extinguish fires and to cool and moisten burns. The breath-ability greatly reduces heat build inside the suit providing extended comfort for prolonged use. This action deprives flames with a fuel source and provides a rigid structure for the component polymers to adhere to.
It is the responsibility of the user to select garments which are appropriate for each intended use which meet all health, safety and regulation requirements.
