Ambient sound can make a space feel calmer or more pleasant, and selected natural sounds may support short-term relaxation. But sound is not automatically beneficial just because it sits in the background: its source, volume, timing, personal meaning, and setting all matter. Unwanted noise can disturb sleep and is associated with health risks, while evidence that ambient audio reliably improves focus or sleep remains limited.
What ambient sound is used for
Ambient sound describes the sound present in a space, whether it is part of the environment or deliberately played. Natural sound exposure can mean hearing rain, birds, waves, wind, or running water live or through a recording, indoors or outdoors. It is broader than listening to a particular “ambient” track.

People may choose sound to create a pleasant atmosphere, take a restorative break, or make a specific disruptive noise less noticeable. Those are different goals: a sound that feels soothing may not mask traffic, and a masking sound is not necessarily relaxing.
Can ambient sound help you relax?
For some listeners, natural sounds are enjoyable and may support short-term emotional or physiological recovery. Health Canada identifies rain, birds, waves, wind in trees, and running water as examples of sounds that can contribute to well-being and stress reduction. Responses vary by listener and circumstance.

A 2024 systematic review and meta-analysis by Zhu and colleagues selected 15 studies involving 1,285 participants from 1,157 literature records. Its abstract reported lower anxiety, heart rate, systolic and diastolic blood pressure, and respiratory rate after natural sound exposure. It also reported substantial variation among studies, so pooled findings should not be treated as a prediction of what one person will experience. The abstract does not establish that the changes are clinically important.
The authors reported pooled anxiety changes of −2.31 on the VAS anxiety measure (95% CI −2.83 to −1.79) and −12.22 on the State Anxiety Inventory (95% CI −22.46 to −1.98). They also reported pooled changes of −5.46 for heart rate, −11.74 for systolic blood pressure, −13.98 for diastolic blood pressure, and −1.58 for respiratory rate; the abstract does not specify units alongside these latter values. These figures describe pooled study results, not guaranteed individual outcomes. Zhu et al., 2024

Do nature sounds improve focus?
That is not established. In a 2023 experiment with 26 participants whose mean age was 21.5 ± 1.9 years, attention-task scores did not differ significantly between nature and urban sound conditions. Several physiological and self-reported relaxation measures favored nature sounds, but this one-session study does not show that nature audio improves productivity or concentration over time. Song et al., 2023

Can ambient sound improve sleep or mask noise?
Intrusive sounds can make it harder to fall asleep or stay asleep. Health Canada notes that sudden or intrusive sounds are more likely to disturb sleep than continuous, quieter sound, and that a sound with personal meaning may be disruptive even at a low level. Individual responses differ.
White noise is one possible way to mask a disruptive sound, not a guaranteed sleep aid or a treatment for insomnia. A white noise machine is an optional way to play it; a dedicated device is not required by the guidance. Other practical measures Health Canada lists include insulating walls, floors, and windows; temporary earplugs; turning off sound from electronic devices; and adding soft surfaces such as rugs or pillows.

A controlled field experiment published on October 6, 2026, studied working professionals in a traffic-exposed rooftop gazebo in Singapore. After a 30-minute break with natural sounds broadcast through a validated system, a heart-rate-variability difference persisted up to two hours after sleep onset that night; it was no longer evident the following day. This specific, short-term result is not proof of lasting sleep improvement or a reason to expect the same effect from a recording at home. Ang et al., 2026

Environmental noise is not necessarily harmless because it is familiar or continuous. The World Health Organization identifies road, rail, and air traffic and building sites as important sources. It says excessive noise can cause annoyance and is associated with risks including ischemic heart disease, hypertension, sleep disturbance, hearing impairment, tinnitus, and cognitive impairment. These are risk associations, not a claim that any particular exposure inevitably causes disease. The WHO page cites an estimate of one million healthy life years lost in 2011 from traffic-related noise in the western part of Europe; that figure is neither global nor a current annual estimate.

Clinical and restorative-environment discussions also explore sound as a supportive feature of settings, but they do not establish ambient audio as a general medical treatment. Short exposure studies, varied methods and populations, and inconsistent cognitive findings limit how broadly the results can be applied. 2021 narrative review of sound in restorative natural environments and 2018 qualitative study of sound in health-care settings
How to choose a sound for your setting
| Goal | What to try | What to keep in mind |
|---|---|---|
| A more pleasant atmosphere or short break | Try a natural sound you enjoy, or choose quiet. | Preference is personal; evidence supports possible short-term relaxation, not a guaranteed effect. |
| Masking a particular disruptive sound | Try white noise or consider physical changes such as insulation, soft furnishings, or temporary earplugs. | Masking is an option, not a treatment; the sound and the source of disruption matter. |
| Better concentration | Compare quiet with a comfortable sound in the task and setting where you need to work. | Current findings do not show a consistent attention benefit from nature sounds. |
| Less disturbance during sleep | Address sudden or intrusive sources where possible; consider the sleep-environment measures Health Canada lists. | Sound with personal meaning can disturb sleep even when it is quiet. |
There is no universal best choice among nature sounds, white noise, music, other continuous sound, or silence. If you experiment, notice whether the option actually helps with your specific goal in that setting, rather than assuming that more background audio is better.
Nature sounds in shared spaces
The Singapore field experiment illustrates a different use from personal listening: adding a nature soundscape to a noisy urban break space. It offers an early example of environmental sound design, with a limited-duration HRV finding in a specific group and location. It does not establish a general design standard or demonstrate lasting health benefits for workplaces or public spaces.
