Campos Electromagnéticos (CEM)

Determinación de la necesidad de realizar una evaluación específica de campos electromagnéticos (CEM) en el lugar de trabajo, según la normativa específica. La aplicación tiene como objetivo orientar al usuario sobre la necesidad de la realización de la evaluación de riesgos específica según lo indicado en el Real Decreto 299/2016, de 22 de julio, sobre protección de la salud y la seguridad de los trabajadores contra los riesgos relacionados con la exposición a campos electromagnéticos. Según se indica en la citada normativa, la evaluación debe realizarse en los puestos donde los trabajadores estén o puedan estar expuestos a CEM como consecuencia de su trabajo. Cuando un equipo emisor de campos electromagnéticos esté destinado a utilizarse por la población general, debe cumplir con la legislación europea, concretamente con la Recomendación 1999/519/CE relativa a la exposición del público en general a campos electromagnéticos, incorporada a nuestra legislación en el Real Decreto 1066/2001. Esta normativa limita la intensidad de los campos para que la exposición a los mismos no cause efectos adversos para la población, con lo que los índices establecidos para el público en general son más estrictos que para los trabajadores. Por este motivo, en los lugares de trabajo con equipos e instalaciones que cumplan con dicha normativa, no será necesario realizar una evaluación específica de CEM. Sin embargo en otros lugares de trabajo, sí puede existir un riesgo de exposición a campos electromagnéticos para los que será necesario realizar una evaluación específica a CEM. La aplicación se basa en la información incluida en la Guía Técnica para la evaluación y prevención de los riesgos derivados de la exposición a CEM en los lugares de trabajo.

All frequency sound generator tools in one app! Tone generation, sound tests, musical tuning and many more. This app helps if you are looking for generating sounds in different frequencies, analyzing sound and making sound tests which produce sound waves based on the desired tone. Frequency sound generator includes user-friendly and very high-quality tone generation tools: • Single frequency generator • Multiple frequency tone generation. • Musical notes presets • Binaural beats • SFX sound generator • Sweep generator. • Bass/Subwoofer sound test • DTMF tones • Metronome • Noise generator Features: • Play sound in background: Play your frequency generation sounds in the background while your app is minimized or your screen is off. • Export all generated sounds to an audio file that you can share. • Animated wave in the single oscillator tool. • Frequency generator effects such as Vibrato (FM), Tremolo (AM), Ring Modulation (RM) and also Pulse Width Modulation (PWM) - for square wave only. • Noise generator effects such as auto-pan and breathing effect. • Play up to 15 oscillators at once in the multi oscillator tool. • Play up to 15 sweep oscillators at once. • Tap your tempo in metronome. Commonly used for: • Make you own experiments with sound generation. • Testing own hearing. Human ear is capable of hearing frequencies between 20Hz to 20000Hz. • Use this app as an instrument for playing or producing music. • Tune your musical instruments with musical notes presets. • Test speakers for high end (treble) and low end (bass) tones. • Discover how your audio handles sweeps of frequencies which range from ultrasound to infrasound. • Relax with binaural beats which play different frequencies in each ear. • Find a way to mask your tinnitus frequency. • Or have fun generating random sound effects, different frequencies and exploring all tone generation tools in this app. • Relax with white noise, brown noise, blue noise, violet noise, grey noise or pink noise playing in the background. Notes: • This app supports decimal values as input for frequencies when generating a tone. • This app makes an animated sound wave which tries to visualize a current frequency. • There are several waveforms available: sine, square, triangle and sawtooth. • Clean UI makes navigation simple through the navigation bar or pages where there are more frequency sound generating tools available. • Customize how the app behaves through settings menu where you can change themes, enable octave buttons, decimal points and more. • Phone speakers are not high-quality audio sources and may vary in quality. Sometimes a "parasite" noise can be generated by those speakers in very low or high frequencies which don't define the frequency. • Turn the volume down when creating high frequencies to not cause any discomfort when experimenting with the app. Privacy policy: https://www.frequencysoundgenerator.com/privacy Terms of use: https://www.frequencysoundgenerator.com/terms

Verdict
The clearest difference is in-app purchases: Campos Electromagnéticos (CEM) at none against Frequency Sound Wave Generator's 3. Campos Electromagnéticos (CEM) also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Frequency Sound Wave Generator's advantage is update cadence (monthly vs every 16 months). On price and device support there is nothing between them.
