Outdoor Sound Systems for Schools: Learning, Play and Wellbeing with the Sound Mixer
Imagine a school playground where children can independently choose a story, listen to a poem, play music or start a calming birdsong recording—all without needing a teacher to find a phone, open an app or connect a portable speaker.
The Sound Mixer is a waterproof, renewable-energy-powered outdoor sound system designed specifically for schools. Pupils can operate its simple illuminated controls themselves, while staff remain in charge of the available content and maximum volume.
Installed alongside the Power Mixer, it turns energy generated from the sun and wind into music, speech and sound that can support learning, play, performance and wellbeing throughout the school day.
What is the Sound Mixer?
The Sound Mixer is a robust audio unit suitable for installation in school playgrounds, outdoor classrooms and other learning environments.
Its straightforward controls allow children to:
- Switch the unit on
- Play or stop a recording
- Move to the previous track
- Move to the next track
An e-paper display shows the selected category and track, while a built-in speaker plays the chosen recording.
The system is designed so that pupils can use it independently. Teachers decide which collection of sounds is available and set the maximum volume, but children can control playback without needing an adult, phone or app.
This provides pupils with a genuine sense of ownership while ensuring that the school retains control over both content and sound levels.
A sound system that becomes part of the school day
The Sound Mixer can be loaded with the school’s own choice of music, spoken recordings and sound effects.
These are organised into categories, allowing the same unit to serve different purposes at different points in the day. A school could create categories such as:
- Music
- Stories
- Poems
- Prayers
- Birdsong and nature sounds
- Relaxation
- Languages
- Curriculum recordings
- School announcements
- Pupil compositions
Staff can select the appropriate category at the unit, after which pupils can move between the tracks contained within it.
This means the Sound Mixer could play a gentle dawn chorus as children arrive, provide poems during a literacy lesson, offer music at lunchtime or play a chapter from an audiobook at the end of the day.
Every school can organise and name its categories differently, making the system adaptable to its pupils, curriculum, routines and ethos.
An outdoor sound system children can operate themselves
One of the Sound Mixer’s most distinctive features is its simplicity.
The four illuminated controls are immediately understandable:
Power
A pupil presses the power button to switch on the unit.
Previous
The previous control returns to the preceding recording within the selected category.
Play and stop
The central control starts or stops the chosen recording.
Next
The next control moves forward to the following recording.
Children can therefore operate the Sound Mixer without navigating menus, handling expensive devices or asking a member of staff to manage the music.
This can encourage independence, decision-making, cooperation and turn-taking. Pupils must listen to one another, share control and agree what should be played next—valuable social skills disguised as pressing a large, brightly coloured button.
Teachers remain in control
Although children control playback, staff control the important settings.
Teachers choose the active category and set the maximum volume directly at the Sound Mixer. Once the limit has been selected, pupils cannot increase the volume beyond it.
There is no app to open and no personal phone needs to remain connected while the system is being used. The selected volume limit remains in place regardless of who presses the controls.
Pupils can enjoy independence without the playground unexpectedly becoming Glastonbury.
How can the Sound Mixer support outdoor learning?
Sound can be an enormously useful teaching resource, particularly when it becomes part of an interactive outdoor environment.
Literacy and spoken language
Teachers can upload poems, stories, phonics activities, vocabulary recordings or passages being studied in class.
Pupils could listen to a poem before performing it themselves, follow part of an audiobook or hear recordings made by other children.
The system can support careful listening, spoken-language development and discussion. It can also give reluctant readers or performers another way to participate.
Music and performance
The Sound Mixer can provide music for outdoor performances, drama activities, dance, movement sessions and informal play.
Schools could upload backing tracks, pupil compositions, instrumental recordings or music relating to a particular cultural or curriculum theme.
An outdoor classroom could become a small performance space without staff having to carry portable speakers and audio equipment outside for every activity.
Languages
Recordings can include vocabulary, songs, conversations and pronunciation exercises in different languages.
Pupils can listen, repeat and practise together, helping spoken language become part of outdoor play and learning rather than being confined to a classroom lesson.
Science and nature
The Sound Mixer can play birdsong, animal calls, weather sounds or recordings from different natural environments.
Pupils could identify species from their calls, compare natural habitats or use sound as the starting point for discussions about wildlife and the environment.
Creative play
Music, stories and sound effects can stimulate imaginative play.
A recording might transform an outdoor shelter into a forest, spacecraft, castle or underwater world. Children can use sounds as inspiration for storytelling, role play, movement and collaborative games.
Supporting calm and wellbeing
The Sound Mixer can also contribute to quieter spaces within a school.
Gentle music, nature recordings, guided breathing exercises or familiar spoken audio could be used within:
- Sensory gardens
- Nurture spaces
- Quiet playground areas
- Outdoor classrooms
- SEND inclusion environments
- Reflection areas
Schools remain entirely in control of what is uploaded, allowing them to choose sounds that are suitable for their pupils and established wellbeing approaches.
For some children, familiar and predictable audio can help create a welcoming routine. A calming recording at arrival time or during a quieter part of the day may help an outdoor space feel more settled and purposeful.
A renewable-energy-powered sound system
The Sound Mixer has no independent power source. It is installed with and connected directly to the Power Mixer, which harvests energy from a wind turbine and solar panel and stores it in a battery.
This means the Sound Mixer provides a visible, everyday demonstration of renewable energy being put to practical use.
Pupils can see that electricity generated from the sun and wind is not simply producing figures on a display—it is powering the stories, poems and music they are hearing.
This creates useful links with learning about:
- Renewable energy
- Electricity
- Battery storage
- Energy consumption
- Sustainability
- Environmental responsibility
The Sound Mixer and Power Mixer therefore work particularly well as part of an outdoor STEM area or Eco Hub.
How is content added?
Staff connect a phone, tablet or laptop to the Sound Mixer’s own password-protected Wi-Fi network.
There is nothing to install and an internet connection is not required. Once connected, authorised staff can create categories and upload MP3 recordings.
Each category can contain up to 64 tracks, giving schools considerable flexibility over the amount and variety of audio available.
After the content has been uploaded and the appropriate category selected, pupils use the illuminated controls on the unit itself. They do not need access to the staff settings or the device used to upload the recordings.
Schools are responsible for ensuring that music and other protected recordings are used under the appropriate licence.
Designed for indoor and outdoor installation
The Sound Mixer is housed in a waterproof enclosure, making it suitable for permanent installation both indoors and outdoors.
It includes:
- Four illuminated, child-friendly controls
- A power button
- Previous, play/stop and next controls
- An e-paper information display
- An integrated speaker
- Password-protected Wi-Fi for staff setup
- Adjustable volume limits controlled by staff
- Automatic power management
- Space for up to 64 MP3 tracks within each category
The unit switches itself off when it is not being used, helping to conserve the renewable energy stored within the Power Mixer battery.
Where can the Sound Mixer be installed?
The system is particularly suited to:
- Primary school playgrounds
- Outdoor classrooms
- Sensory gardens
- Nurture and wellbeing spaces
- SEND inclusion areas
- Performance spaces
- Quiet areas
- Eco Hubs and outdoor STEM environments
It can form part of a new outdoor development or be considered when enhancing an existing learning or play area.
Because it must be connected directly to a Power Mixer, the two systems are planned and installed together.

Can pupils change the volume?
Children can control playback, but staff set the maximum permitted volume. The volume cannot be increased beyond the limit chosen by the school.
Does it need an app?
No. There is no app to install or account to log into. Staff connect to the unit’s own password-protected Wi-Fi when they need to upload content or change its setup.
Does it require an internet connection?
No. The Sound Mixer creates its own local Wi-Fi connection for authorised staff. The school does not need an internet connection to upload or manage recordings.
How many recordings can it hold?
Each category can contain up to 64 MP3 tracks. Schools can create and name categories to suit their curriculum and daily routines.
Is it suitable for outdoor use?
Yes. The Sound Mixer has a waterproof enclosure and is designed for permanent indoor or outdoor installation.
How is the Sound Mixer powered?
It is wired directly to the Power Mixer battery. It does not have a separate power supply and cannot operate without a Power Mixer, so the two systems are installed together.
Can schools upload their own recordings?
Yes. Schools choose and upload their own MP3 content. This could include music, stories, poems, prayers, curriculum recordings, pupil compositions or appropriate sound effects.
Give pupils the power to choose what they hear
The Sound Mixer brings together outdoor learning, creative play, pupil independence and renewable energy in one distinctive system.
Children are given simple, meaningful control over the sounds they hear, while teachers decide what is available and how loudly it can be played.
Whether it is used for a poem in an outdoor literacy lesson, music during lunchtime, a story at home time or gentle birdsong within a sensory garden, the Sound Mixer allows each school to create an audio environment of its own.
The Sound Mixer is built by Electric Pedals and delivered for school environments in partnership with The Hideout House Company.
