## Bullerkollen Description
Bullerkollen is an indicative sound level meter for iOS that turns your phone's built-in microphone into a practical measurement tool for noise, acoustics and vibration.

  SOUND AND NOISE MEASUREMENT
  Measure with A- and C-weighting according to IEC 61672-1. The app calculates LAeq, LAFmax, LCeq, LCpeak, LASmax, LAFmin, L10, L50, L90 and LAE (SEL) in real time. Choose measurement duration (5–60 seconds) and save results with a name and notes.

  1/3-OCTAVE SPECTRUM
  View A-weighted equivalent level per 1/3-octave band (20 Hz–16 kHz) in a clear bar chart. Perfect for identifying the frequency content of a noise source.

  24-HOUR LOG
  Measure and log LAeq and LAFmax continuously for as long as you need — hours or entire nights. Choose resolution (1 second to 15 minutes) and export a PDF report directly in the app. Ideal for night-time measurements and longer monitoring sessions.

  INDICATIVE INSULATION SCREENING
  Estimate the sound insulation of a wall or floor (DnT and R') as a single-number value according to ISO 717-1. Use a Bluetooth speaker as the source and measure in source and receiver rooms in five steps. Import reverberation time from Akustikkollen or enter
  manually.

  VIBRATION METER
  Measure linear acceleration (m/s²) using the phone's accelerometer. Shows live RMS, measurement RMS per axis (X/Y/Z) and comfort class according to ISO 2631-1 — indicative screening of whole-body vibration.

  CALIBRATION
  • Device profiles for known phone models (based on NIOSH data)
  • Calibration against a reference sound level meter
  • Manual dB offset
  • Support for external measurement microphones with calibration curve (.cal / .csv)

  BBR COMPARISON
  Compare measurement results against Swedish Public Health Agency guidelines (FoHMFS 2014:13) for bedrooms and other rooms — directly after each measurement.

  SAVE & EXPORT
  All measurement history is stored locally. Export individual measurements as CSV. 24-hour logs and insulation measurements export as PDF reports.

  IMPORTANT
  Bullerkollen is an indicative meter and does not meet the requirements of SS-EN 61672-1 for Class 1 or Class 2 sound level meters. Do not use this app as the basis for regulatory reports or inspection protocols — use a calibrated meter and consult an acoustics
  professional when required.

  Bullerkollen is developed by B&L Lund AB, a consulting firm specialised in acoustics, noise and vibration.
