Not frats only. I'm not in a frat but I do want to make a case that it isn't just frats as I can see a veiled attack (either intentional or unintentional) towards frats.
I DJ on a semi-frequent basis and hearing is especially a concern. I have very sensitive ears and suffered from a bout of tinnitus from a Techno show a few years ago.
I swear by acoustic earplugs now. Different people have different tolerances to loud music and you should take whatever measure you need to protect your hearing. I always wear earplugs and always make a case for advocacy against hearing damage. What might seem like a small issue now since we're all low-mid 20s will be a huge issue later in life.
I always bring acoustic earplugs with me. They dampen the noise evenly across the frequency spectrum so that you can hear everything without distortion, but to an extent of lesser volume. Etymotic ETY-20s are good. V-MODA VIP Faders are my goto, and Ear Love (http://www.earlove.net/) also sells earplugs. Full disclosure: I've collaborated with earlove in the past and think their company is great.
The other end of the issue would be decibel limits. Most cellphones can't discern dB properly since their microphones usually cap out at ~85 dB, but it might be good to get this app (https://play.google.com/store/apps/details?id=kr.sira.sound&hl=en) to understand the sound in the room.
My results during the day:
Turned off (room noise): 29 dB
Idle: 34 dB
After 30 minutes (playing games): 37 dB
Under load (Rocket League): 45 dB
Edit: further info
Attempt the record noise for evidence.
What the poster seems to be trying to say is, "Attempt to record the noise, for evidence."
This is partly correct. The problem with this is that doing this provides no reference point. In arbitration, questions might arise.
How sensitive was the mic used? Was the audio manipulated in post? How far away from the noise source? How much has it been amplified for playback? How accurate are the transducers and the playback-device? (Remember that RTB arbitration hearings are typically conducted by phone)
What you need to do is to document and time-stamp the noise level, in decibels. You'll need to use a Sound Pressure Level meter for this. You can get an app on your smart phone, or a stand-alone one, if you don't own a smart phone.
When the noise starts up, you then document it with a time-stamped video with comparable audio, as a reference point. Television or radio news running at a normal level is excellent for this contrast.
I'm not a developer, but I believe Android apps do know what device is using the app as I recall emulating a Samsung Galaxy Note 9 to play Fortnite on Android during Early Access!
Anyways, I currently use this Sound Meter app on Android, and it appears like they do calibrate for each device.
>Since 2010, we had calibrated the app on 500+ android devices (Major Galaxy, LG, Xperia, Motorola and Nexus).
Of course, I understand that there is still variance on each individual unit, but for the purposes of measuring an approximate dB level for safety purposes, it should be sufficient.
Cada reglamento municipal debe de incluir el nivel máximo de decibeles en tu zona. Las zonas residenciales tienen menos toleranccia que las conurbadas, hay horarios etc.
Por ejemplo en monterrey

En mi oficina nos denunciaron al ayuntamiento por "derramar aguas contaminadas" o algo similar. El menos en Mérida si proceden las denuncias de este tipo y por poco tenemos que pagar multa. En nuestro caso, resulta que uno de los caños del techo derrama agua sobre la barda del vecino y esto supuestamente la había cuarteado. Nos hubieran multado, pero cuando vino el perito resultó que la barda del vecino está hecha sin castillos y sin cimientos adecuados, así que el que pagó multa fue el.
edit: puedes medir cuantos decibeles genera la bomba con un app
> Great idea and something substantial I could present to my attorney
Note that those things aren't all that reliable. Here is one app creator who is honest about it:
>REMEMBER! Most smartphone microphones are aligned to human voice (300-3400Hz, 40-60dB). Voice calls do not require high-performance microphones. Therefore the maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized.
I have no idea what 'Here Active' thing is, but it sounds like a headphone to me. If it is a headphone, you can measure the estimated output of it by using a Sound Meter app.
Download from Play Store for your Android: https://play.google.com/store/apps/details?id=kr.sira.sound
Or search for one on the App Store if you're on iOS.
Then simply turn on the App, place your phone's microphone close to the sound outlet of the headphones and you'll get the minimum amount of decibels that Here thing is generating. I emphasize minimum, because the distance from the headphone to your ears will be much closer than the distance between the microphone and the headphone during the test. You could around 10-20 Decibels to whatever result the sound meter shows you, to arrive at a good estimate of the output of that white noise.
Let me know if I have completely misunderstood Here.
There are sound level apps on most platforms with Db meters. Work with almost all smartphones. Example
The distance away matters to get within the dynamic range of the phone mic.
Awesome print! It'd be cool to test the relative decibel meter before and after the enclosure. We have a few in the office and I was thinking of building an enclosure to reduce noise levels.
Maybe an app like this would help? Would love to see the results.
Of course, you're welcome! I'd say one easy way to gauge if you're mild would be if you can tolerate most noises, just not extremely loud ones (including sound coming out of speakers, phones, etc.). For example, if loud vehicles like garbage trucks, motorcycles, etc. driving by as you're walking down the street (without hearing protection) don't bother you or cause you pain, you're probably mild. If you immediately are experiencing discomfort or pain when vehicles like that pass you by, you may have moderate H (and will want to wearing some hearing protection like Earasers when out and about). If it's extremely distressing, with prolonged pain (lasting weeks or months) from that kind of brief noise exposure that you'd encounter in daily life, you may be on the more severe end of things. If that's the case, you'll want to be wearing foam plugs and possibly ear muffs too. I recommend Moldex Pura Fit or SparkPlugs and Peltor X5A. Even if you're definitely not severe, having quality hearing protection is useful for louder situations, such as vacuuming, using power tools, etc.
Probably a safer test that you can self-administer would be to start up a decibel app on your phone (if on Android, the free Sound Meter app is what I use) and to turn on some speakers (ideally a home theater system). Put on a favorite song of yours, slowly turn up the volume level until it causes you immediate discomfort, quickly reference what it says on the decibel app, and pause the song to avoid hurting your ears. Report back if you want to. It's all speculation, but anything under probably 60db is evidence of moderate H. If you immediately feel discomfort when putting the song on (even pretty quietly), you may be on the more severe side of things. If you can easily handle 75db, it may be more mild. If it takes like 90db to cause you discomfort, I'd say with confidence that your H is mild.
To add to the suggestions about logging any loud noise, this may help. A Sound Meter app that measures decibels (dBA). It will help no end in quantifying 'loud' to the council. (Apple store has similar).

I use Sound Meter as it's supposedly got a calibration for my model phone that makes it decently accurate. https://play.google.com/store/apps/details?id=kr.sira.sound&hl=en
Additionally, OSHA publishes a more nuanced exposure chart for sound. Keep it under 85DB A weighted people.

No, your phone has no idea what kind of headphones you are using or if they are amped in some way.
There are decibel meters that would allow you to hold your earphone to your phones microphone to get some idea of how many decibels you are putting out. Would not be very accurate.

Using Sound Meter for Android (https://play.google.com/store/apps/details?id=kr.sira.sound&hl=en) my rack measures 63dB inside the rack right behind both the US-48 and US-16-XG.
From about 3 feet away me whole rack measures 46dB.
There's a hollow core door about 3 feet from the rack, and my living room is right on the other side, this is a big reason why I needed low power/quiet components as much as possible. With the door shut and sitting on my couch I can't even hear my rack.
I traded a Synology expansion bay (DX510 with 5x2tb drives) for my XG. That plus the low Synology cost are what kind of kick started this whole project.
I have an H220 LCU in an R4 case (same as main OP) and it's right on the desk next to me, I feel like it's pretty quiet but I decided to do a little test to see. I put the sound meter right on top of the case pointed at the vents where my radiator is. With the PC (and ceiling fan) off in the room it sits at about 33 dB. Once the PC is on, goes up to 66-67 dB. Definitely louder, but I wouldn't actually call it "loud." I'd be curious to see what other people's sound levels are like (I used this app.)
With my s6(no case) just sitting on my desk. Playing full volume I opened audio meter and it showed 89db I dont know it that is accurate since the speakers are right next to the mic and it looked like the audio pegged the meter out. It might at least give you a base line for where it is at though.
Thanks! That actually makes sense and helps me understand this chart a bit more. I cant really tell what 0 is!
I got the 45 from an App I dl'ed off the market (sounds so stupid now) and without calibrating it showed me 45.
On one of the meters it says
20 is rustling leaves,
30 is quiet whisper at 3ft in a Library,
40 is Quiet residential area,
50 is quiet office
60 is Normal conversation at 3 ft
70 Busy traffic
Looking back 45 makes no sense because its actually pin drop silence where I live. So I can calibrate and set the sound pressure lower so it reads 25ish ambient which puts my whispers at 32 (which matches the scale), my mouse at 36 (3 cm away from it), and my keystrokes at 45-49 (Mechanical Keyboard Cherry Reds).
Do these numbers make more sense?
EDIT: Put in the Link to the App I used
Might I suggest the following?

I have an older analog meter. Think I'll try one of the apps and see how they compare. A search for SPL Meter or Sound Meter should yield many options. Then either take a photo of the meter or a screen capture.
Try and catalogue incidents. Something like this may help. https://play.google.com/store/apps/details?id=kr.sira.sound&hl=en_GB
I genuinely feel for you though.
I use a sound meter for just fucking around with. I don't think it can do what you want, but here it is. Sound Meter

The pro version of this does logging. I've used the free version and found it pretty decent.
There's probably an app for that.
