    Insomnia treatment consist mostly of sleeping pills consumption but this circuit is an alternative for that and consists of a simple circuitry that generates a rain sound effect. The japanese researches were the first to discover that sound of rain has a relaxing effect. With the help of this simple circuit we can generate the rain sound which can be a sleep aid in case of insomnia.

    T1 is used as a noise generator and its signal is amplified by the 741 IC and thru T2, R7 and C4 goes to a headset with low resistance. If you do not want to use the headphones then use a speaker with impedance between 4 and 16 Ω. With the help of P1 can adjust sound level and with P2 the tone.

    1. woops–I think you have a problem with the output connection…

    2. I voted with yes because the rain sound it really is a sleep aid in my case. For example in rainy days I feel so sleepy that I just can’t stay awake.

    3. There should have been another option: I do not know, have to find out


    5. what is C4,P2 and P1 in the circuit diagram?
      help me as early as possible….

        C4 is an aluminum electrolytic capacitor.
        P1 & P2 are potentiometers wired as rheostats (variable resistors).

    6. Which component in this circuit produces such specific sound?

    7. How much will this circuit cost? If I get some approximation only then I can decide whether to make it in my mini or major project.

    8. Could it be used with 1.5 or 3 volt battery?
      If not,pl give one which will work with 1.5 to 3VDc.

    9. @ p mariam, can u pls upload d modified cct diagram?

    10. This is not working. You sure there is no mistakes?

    11. the sound the rain is incredibly pleasing it does tend to put me to sleep

    12. hi p.marian

      I am a electronics and communication engineering student i am working in rain sound generator circuit but i can not understand actually what is P1 and P2? Can u please tell me as soon as possible…?


    13. what is the right-bottom symbol (with 4…32 ohm) mean? thank you.

    14. nice your circuit

    15. how the circuit generate the rain sound. can we change the transistor 2N1613 with other transistor?

    16. aren´t the IC741 No. wrong? the LM741 i have has has only 8 pins.

    17. the pin numbering of IC 741 is wrong. IC is generally available in 8 pin package.
      please refer any other ciruit using IC 741 or its datasheet.

    18. replacement for transistor 2N1613 please reply soon

    19. Can you please tell me a replacement for the transistor 2n1613?

    20. could you please tell me the values of the resistor variable you using

    21. The circuit perfectly.
      Try 2N1711 if 2N1613 not available

      Hi. I made this circuit for a college project and it works brilliantly. But I need detailed working of this circuit. Can you please send me the detailed working?

    23. Hi, Vicky can u send me the details bout this circuit?

    24. Hi, Vicky can u send me the details bout this circuit?? Thanks

    25. could anyone please tell me a replacement for 2N1613
      even 2N1711 is not available. Please respond Asap.
