Hearing Aid
Product Code : SCL-BLE-11743
Hearing Aid (SKU SCL-BLE-11743) is a sound-amplifying unit that raises sound levels by up to 40 decibels and offers six volume settings, with low-frequency noise control. In biology and health-education lessons it gives students a working device to discuss how the ear detects sound and how amplification helps reduced hearing. Science Lab Supplies sources and dispatches it from Ambala, India for school laboratories, colleges, training institutes and lab tender contractors.
Specifications
The table lists each specification of the 40 dB hearing aid. In short, it amplifies sounds by up to 40 decibels, has six adjustable volume levels, a slope-type response shaped to the frequency response of hearing loss, and low-frequency noise control for clear, low-noise output with simple operation.

Applications and Experiments for the Hearing Aid
The hearing aid serves as a demonstration device in lessons on the human ear, sound and hearing. Students can step through its six volume levels to hear how amplification changes loudness, then relate the 40 dB figure to the decibel scale. It suits school biology lab equipment in India for sense-organ topics.
- Class 8–10 science: sound, loudness and the decibel, alongside the structure of the ear on the Human Ear Model 5 Parts.
- Class 11–12 biology: sense organs and the hearing mechanism, discussing why reduced hearing calls for amplification.
- Physics of sound: comparing frequency and loudness using an Audio-Frequency Generator or the Tuning Forks Pair with Resonator.
- Nursing and health-education courses: introducing how hearing aids work in general terms.
Start every demonstration at the lowest volume level and raise it gradually, keeping the unit away from the ear at higher settings.
Standard Scope of Supply
The hearing aid is supplied as a single unit with the six-level volume control and noise-control features described above. Any batteries, spare parts or optional accessories are named on the quotation, so the buyer knows exactly what each unit includes before ordering.
Packing, MOQ and Lead Time
Ask for a quotation for one hearing aid for a demonstration bench or for several units for a teaching programme. Science Lab Supplies sets out the packing, delivery time and price for the exact quantity, and ear models or tuning forks can be priced on the same quote.
With its Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Send your quantity using the contact page, save the item to the enquiry cart for a combined list, or read the lab tender page for bid paperwork.
Frequently Asked Questions
How much does the Hearing Aid amplify sound?
It amplifies sounds by up to 40 decibels. Six adjustable volume levels let the user choose a lower or higher setting within that range, which makes the change in loudness easy to demonstrate in class.
What does the noise control do?
The unit has low-frequency noise control and a slope-type response shaped to the frequency response of hearing loss, intended to keep the output clear and low in noise across a wide range of sound levels.
Who supplies this hearing aid?
Science Lab Supplies, based in Ambala, India, provides it as a supplied item for schools, colleges and training centres, and prices it item by item alongside other biology equipment on one quotation.
Is this unit intended for clinical fitting?
It is offered as teaching equipment for lessons on hearing and sound. For any personal or clinical use, a qualified audiologist should advise on a suitable device and its fitting.
