About this app
SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume. We had calibrated many android devices with the actual sound level meter with dB(A).
REMEMBER!! The smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB).
Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB), HTC Desire(82dB)...
Vibrometer app uses the phone sensors to measure vibration or the earthquake, and it shows a reference as a seism detector.
The measured values are the Modified Mercalli Intensity scale(MMI), and just for reference.

Rd কতই তো ইচ্ছে করে, তোকে বুকে জড়িয়ে রাখি। কিন্তু ইচ্ছে করলেই কি হবে? তুই তো মানতেও পারিস না, জানতেও চাস না, কতটা ভালবাসি। হিসেবের খাতায় বরাবরের ভুলের মতো, আরেকটা ভুল করেছি তোকে ভালবেসে। যতবারই তোকে ভুলে যেতে চাই, মনের আকাশ পাতাল জগাখিচুরি হয়ে শুধু তোকেই মনে পড়ে। আজ হাল ছেড়ে দিলাম। আর কখনো বলবো না তোকে ছেড়ে চলে যাবো, অথবা ভুলে যাবো তোকে। বলবো, কখনো যদি কাউকে ভালবাসি, তবে তোকেই আবার এবং বারবার ভালবাসবো।।
