Have you ever realized how loud your life is? Whether it’s the construction down your street that’s been going for years, or the constant wail of the Caltrain passing by, or even just the whispered chatter during “silent work time” in all of your classes; noise is something we can never really escape.
As the United States Environmental Protection Agency (EPA) puts it, “The air around us is constantly filled with sounds, yet most of us would probably not say we are surrounded by noise.” That explains why noise pollution is so rarely discussed, despite its undeniable potential to influence communities. Both on an individual level and a much broader scale, volume makes a difference.
Palo Alto, a populated suburb and global tech hub just outside of San Francisco, is no stranger to noise. It is something the city acknowledges — and attempts to resolve — in the City Of Palo Alto Noise Ordinance issued in 2010. The declaration of policy, “Is that the … citizens of Palo Alto require protection from excessive, unnecessary and unreasonable noises from any and all sources in the community.”
By announcing that protection is needed, the policy implies some greater looming threat. It helps to define what exactly makes sound such a problem. According to the EPA, “Sound becomes unwanted when it either interferes with normal activities such as sleeping, conversation, or disrupts or diminishes one’s quality of life.” Put simply, something worth complaining about equals a failure on the protection front.
But where are these irritating sounds coming from? According to a 2025 Sound Fighter Systems article, the central causes of noise pollution are “road traffic and transportation, construction activities, industrial and manufacturing noises, and urban development and public infrastructure.” All of which are not abstract or easily preventable; but rather unavoidable aspects of everyday life.
Realistically, we cannot ask people to stop building houses and apartments or drive more quietly. The most that can be done is to set rules and regulations. In Palo Alto, for residential properties, no person may produce or suffer a noise level higher than 6 dB above the local ambient, and for commercial and industrial properties, 8 dB above.
This just might be enough to combat the potential health problems associated with noise pollution, some of which are “… stress related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity” (EPA).
But while it’s an easy enough fix for humans to put some guidelines in place, it can be much harder for other parties to deal with and overcome the adverse effects of noise pollution.
The animal life and ecosystems that surround our city are greatly impacted.
According to PBS news in the 2017 article How noise pollution from humans is wreaking havoc on U.S. wildlife, noise pollution, “reduces the ability to hear natural sounds, which can mean the difference between life and death for many animals.”
One example of this is baleen whales, a species renowned for their acoustic communication. In a 2024 article published by the National Institute of Health titled Avoidance, confusion or solitude?, it is stated that, “Given the importance of sound for communication and information … noise pollution is believed to have a broad spectrum of impacts on whales (and other marine animals).” There has been a reduction in communication range, physiological damage and stranding events, and additionally “altered swimming behavior due to noise avoidance responses.”
Of course, there are also local examples of noise pollution’s influence on ecosystems. In September of 2024, the Palo Alto Airport expressed a desire to extend the runway into the Baylands. The Mountain View Voice covered the topic and the related letter submitted to the council by a collection of nonprofits, which stated, “Palo Alto should not un-dedicate parkland, fill wetlands, increase the risk to birds or the need to deter them from using the adjacent wetlands, exacerbate noise, or perpetuate lead deposition and greenhouse gas emissions.”
The council heard their concerns, and the proposal was ultimately rejected. As council member Vicki Veenker explained, “The community rallied around our beloved Baylands.”
Ultimately, the most we as a community can do to combat noise pollution is to put our support where it is needed, and follow through on guidelines put in place. And because most noisy human activities show no sign of slowing as society continues to progress, the most realistic solution is to quiet down what we already have. Noise is everywhere and a part of everything, but that doesn’t mean we can’t learn to tune down the volume.
