Our constant exposure to alarms and alerts in today's noisy world can have significant effects on our minds and bodies, increasing stress levels and even leading to symptoms of ADHD.
Hospitals are filled with disruptive noises that can cause stress and anxiety for patients and medical staff, but efforts are being made to create a calmer and quieter environment, including the creation of Tranquility Rooms.

The Impact of Constant Alarms and Alerts
In today's noisy world filled with alarms and alerts vying for our attention, the constant interruption and acoustic intrusion can have significant effects on our minds and bodies. Shrill and loud sounds stimulate more nerve cells, increasing stress levels and arousal. Even seemingly innocuous sounds can create a stress response if they hold personal meaning. Studies show that the constant distraction and habit of reacting to alerts can lead to symptoms of ADHD. This phenomenon, known as 'ring-xiety,' causes individuals to mistakenly hear their phones ringing. However, some people develop 'inattentional deafness,' where they unconsciously tune out the overwhelming sounds and stimuli. Our relationship with devices has become compulsive and addictive, as alerts provide a sense of social connectedness and relieve the stress of feeling unconnected. Despite the negative impact, it is crucial to be mindful of the alerts we invite into our lives and prioritize what truly matters.
The Noisy Soundscape in Hospitals
Hospitals are known for their noisy environments filled with alarms, beeps, ringing phones, and various other sounds. These sounds, often reaching 60 to 90 decibels, can cause disturbance, stress, and anxiety for patients and their families. Even the smallest sounds, like card key scans or door dings, add to the cacophony. For medical staff, the constant noise can lead to alarm fatigue, where they become desensitized to the alarms. Furthermore, up to 99% of alarms are clinically insignificant or false positives, creating a tiring environment. Efforts are being made to improve the standard for medical alarms, incorporating natural sounds that convey the event they are alerting for, ultimately aiming to create a calmer and quieter hospital soundscape.
Designing Tranquility in Hospitals
Recognizing the negative impact of noise on patients and medical staff, efforts are underway to reduce stress-based noise in hospitals. One such initiative is the creation of Tranquility Rooms, which provide a space for doctors and nurses to retreat from the noisy environment and find moments of peace. These rooms are designed with soothing music, dim lighting, aroma therapy, and an atmosphere resembling a spa. While it is too early to quantify the reduction in noise levels, early feedback suggests that these rooms have a positive impact on stress levels and well-being for staff members, aiding in creating a better hospital experience for all.
Alarm sounds have been around almost as long as humans themselves. But as our world has transformed, so have they. Today’s alarms are having an unexpected effect on our minds and bodies, and can even be putting our lives at risk when we’re at our most vulnerable. Dr Judy Edworthy and Yoko Sen talk to us about our alarming sound environment, and how it can be improved.
