noise

When it's cold outside, under around 2 Celsius (35,6 Fahrenheit), our neighbors air-to-water heatpump that is located 5 meters (16,4 feet) from our 2 bedroom walls, creates a disturbing rumbling noise that affects peace and sleep inside our bedrooms, even with the windows closed. The unit in...

Current Audio Chain (source to destination): PC -> USB to USB-C Adapter -> USB-C to Micro-USB cable (included) -> Tempotec Sonata HD Pro DAC dongle -> Long audio cable -> S.M.S.L SP200 Amp -> Long audio cable -> HIFIMAN Sundara Issue: I experience significant electrical noise/interference under...

Hi! I'm FiftyTifty, and you might remember me from complaining about power draw causing noise on my speakers. Yeah it's back and I'm at my wits end with it. After getting the Behringer Hum Destroyer and using my Creative soundcard, it was tolerable but was slowly getting more and more on my...

Hi audio scientists, I've been trying to eliminate a ground hum from my desktop system, audible only when I use sensitive iems. I bet someone here knows exactly what to do. I've systematically removed as many components as possible and narrowed it to the headphone amp -- a Sabaj A10h. With...

Edition XS, Fiio TF1 Pro Topping DX3 Pro+ I have had three pairs of PM Headphones at home until know and each of them displayed some sort of resonating noise in either the chassis or the driver itself. I use this tone generator and with all three i found frequencies that agitate some sort of...

When the DAC's line-out is connected to the headphone amplifier, it's signal attenuated by the volume control and raised or lowered by the gain. Thus, using the headphone amplifier can reduce the noise in the signal going to the headphones compared to using the headphone output of the DAC. This...

I've got the Issue that when i try to play audio via USB I'm getting a annoying noise that i can't seem to fully fix. From what i found out could it be caused by the USBs "Framerate", which is 1kHz, but how can i stop it? The only Idea i got is getting a powered USB-Hub, but i wanted to ask if...

Hi everyone, I have a question for you regarding my new pair of TW4. Coming from TW2, i noticed something unusual (at least for me) on this pair. When I turn ANC ON, the simple touch of my earbuds with fingers randomly produces a disturbance/inteference (it's like when radio signal is weak) for...

Yesterday my new order arrived, a Fosi audio k5 pro mini "gamer" audio DAC, I bought it to use with my IEM Truthear zero RED, both to amplify the sound and because its cable is too short to use on my PC. However, when I connect my Truthear to the DAC I hear white noise in the background when...

I don't know if this has happened to anyone, I encountered this problem in two distinct and separate audio systems (both with a TV connected to a Fire TV in between). At a certain point I noticed a background noise, not constant but in the form of discharges, very high in volume and very...

I added balanced outs from my D90 to my preamp. Now when I change tracks and the DAC is changing sampling rates (you see the new sample rate on the display) it makes a crackling noise. This only happens with the XLR, when I switch to RCA I don’t experience the noise. The DAC is making the...

Can a 2x2, 24/96 capable (UAC1) audio interface for a mere 65€ from Thomann's house brand be any good? Well, I just happened to need something to take care of an XLR condenser mic so I could finally liberate the Audient EVO 4 from my office PC and use it for portable measurements again, and I...

Hi there, I have a Hidizs S9 that I bought ages ago for use with my phone, but I haven't used it much because I've never really managed to get it working right. It has a lot of hiss at low volumes when not using exclusive audio mode apps. It's a kind of swish noise that fades up as the track...

Hi, I have got a hiss noise issue coming from the speakers with my current setup that I use for music production (recording guitar and voice), music listening and calls. I think it is due to a USB power leakage but I would like confirmation from experts :) Attached file is a recording of the...

Have met two problems with my home studio monitors, hope somebody can help me out, thanks: 1. The self-generated noise level of my pair of KRK ROKIT 8 G4 is really high. It was so loud that I could hear the noise from the whole room, and couldn't sleep. Have Anyone met the same problem with me...

I live off grid and recently changed my pure sign wave inverter, now I have three times the feedback noise in my system. The noise comes through both 12v, and 115v, power supplied. I had a cheep feedback eliminator that took care of 90% of the noise before. Now is much louder and the feedback...

Hello guys! I have a question about my new Loxjie A30 amplifier. I noticed that when I adjust the volume while music is playing, I hear a noise. When I increase or decrease the volume by one notch, the speakers make a "sizzling" sound. Is this Normal?

Hi, I have an unorthodox setup. I have my computer connected over HDMI ARC to the NAD T748 receiver. Using the receivers RCA pre-outs I connect it with 3m 2xRCA to 3.5mm jack cables to two pairs of KEF LSX speakers for 4.1 surround (Awaiting one LS50 anniversary for center channel). I have...

PCM to DSD = better sound quality?
