While wireless earbuds have come a long way over the past two years, even great ones have issues. They haven't made the leaps in battery life that other wireless headphones have, and given their ...
Because low-income neighborhoods are often at greater risk of noise pollution, the establishment of such zoning codes is often an environmental justice issue. [25] Mixed-use areas present especially difficult conflicts that require special attention to the need to protect people from the harmful effects of noise pollution.
Environmental noise can also convey a sense of liveliness in an area, which can be desirable. The adverse effects of noise exposure (i.e. noise pollution) could include: interference with speech or other 'desired' sounds, annoyance, sleep disturbance, anxiety, hearing damage and stress-related cardiovascular health problems.

A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
The aquatic ecosystems are known to use sound to navigate, find food, and protect themselves. In 2020, one of the worst mass stranding of whales occurred in Australia. Experts suggest that noise pollution plays a major role in the mass stranding of whales. [97] Noise pollution has also altered avian communities and diversity.
Fogel is considered to be the inventor of active noise cancellation, and he designed one of the first noise-cancelling headphones systems. Later on, Willard Meeker designed an active noise control model that was applied to circumaural earmuffs for advanced hearing protection. Noise-cancelling aviation headsets are now commonly available. [5] [6]
Every winter season, it becomes fashionable to blame farmers for Delhi's smog problem. The onus of air quality and good behaviour shouldn't be on the poorest of the poor. The government needs to ...
